If I could give this marina 0 stars I would! Let's start with the snotty, two faced people on B dock, i mean wow! If you want to party with a bunch of 55+ who act like high schoolers, this is the place for you! Otherwise there are much better options elsewhere!

facilities were awesome but had to call front desk to get a gas attendant to pump gas.

We have been at TI for over 20 years! It just keeps getting better every year.

We have a great group of people that make it one of the best marinas around. The casino and entertainment are also very nice to have easy access to. It was nice to see some new entertainment and activities for the marina this year! We are hopeful to see some big names perform next year at the ampatheater.
One idea that may help improve marina services and customer satisfaction as well as improve management accessibility would be to to consider having the supervisor office down on the water where the action is (back area of ship store). It would be wonderful to know there always be someone at the gas dock during business hours. We have had to call the number listed many times to get someone to help us get gas, pump out or even supplies and it is very frustrating. Perhaps this could would free up dock staff to better care for the bathroom and shower areas as well.
On a side note, we have noticed that slip rates are going up yearly, previously we would only notice an increase every few years. We are hoping this won't become the new normal as most boat owners are just regular joes making it work :)
We are very excited to spend another year at TI!

We are new to the marina and are very impressed. It is always well taken care of and everyone is very helpful.

Most importantly...the whole dock now has 50 Amp, 240 Volt power. Normally only slips 1-4 had 240 V, and the rest had 208 V ("Normal for back in the day"). The decking has all been replaced, but some of the stain was transferring to the swim platforms when wet. Nothing major and came off with a scrub. They were a bit understaffed for a Friday afternoon on an expected event weekend, resulting in delayed radio communication and docking assistance. Cool band was playing in the lot on Saturday and the kids loved the waterpark. Overall, pretty nice!

Marina was perfect. Shuttle service to the casino was unreliable.

Celebrated a friends 50th birthday party. Fantastic dinner with 10 people at the Casino restaurant Tado, bean bag tournament and very helpful dock hands as well as support from the facility for our party. Marks the third year of our tradition.

Boat slip was open and waiting for us. Easy to rent!

Nice facility. We enjoyed our stay at the marina. Docks were nice and the amenities were great.

Terrible. C dock electric was very bad. Kept tripping when my ac kicked in. Worked over 2 hours trying to get it to work. One hot night on the boat with no ac. I want a refund and one free night pass for my troubles.
What is wrong with C dock electric?
Got back to Kings Cove and everything is perfect.

TI is always predictablly great. Unfortunately, it looks like there was some recent electrical work done and things aren't quite right. I had one 30amp outlet register as swapped polarity. Second 30 amp did work. However, I had a neighbor whos circuits kept popping. The Marina did allow for changing slips but be warned until they get it ironed out

Please tell me why slip 45 doesn’t have a dock wheel at the end of the slip!!!!! While docking, boat came in contact with the dock and put a nice scrape on my hull. Very disappointed. As I survey the docks, this is the only one that’s missing a wheel. Very disappointed to say the least.

Incompetent dock workers. Unprofessional inexperienced tribal members.

I have been a seasonal slip holder for over 12 years. The Staff have always been great people,
DockWa can use a talking too. Out of 56 slips on C Dock. Why does DockWa always put boats in slips next to the only permanent slip holders?? C dock can be totally empty, if someone books a spot it’s right next to the permanent people.
Spread them out DockWa unless they are part of a group.

The Dock employees are always so nice and very helpful in docking the boats. To be honest I’m very dissatisfied with the cost of Thursday night. My group from Miss Croix (7 boats) will be reconsidering our next year stay. Obviously many people were not going to pay that price because it was dead.

Happy to hear you had fun staying at Treasure Island Marina for the concert! The shuttle runs regularly on weekends and concert days, but if you need a shuttle, there is a phone on the outside of the block bathroom building. Just pick up the receiver and push the speed dial button to be connected to an operator who will send a shuttle. You can also ask any Marina staff and we will be happy to call a shuttle for you. Why do I keep saying the shuttle phone thing? Because I know people read reviews, and it's a great place for us to educate people who may not know how to access amenities. We look forward to seeing you again soon!by Jeff S. - Verified user on Jun 24, 2025
This is our fifth year staying at the marina and the new improvements to the dock are very nice, there is always someone there to help with docking, and the setting is beautiful and peaceful. The price is right too.

The new transient docks were great, but most of our group had electrical problems. People will quit coming back if their a/c doesn't work...

Great marina. The employees were there to greet me upon arrival and told me where to put my trailer after launching the boat. Be careful of very shallow water 50' east of B and C dock. Just stay close to the marina until you get south of A dock.

We had great service at the gas dock and pulling into our slip for the night.
