Facilities were great but problems with electric hookups were frustrating

The marina is too expensive on the weekends. Bathrooms were ok and showers were good.

Thank you for staying at Treasure Island Marina. We are happy to hear you had fun. We hope to see you again soon.by David L. - Verified user on Jun 07, 2026
Staff very new and inexperienced not know how to tie up boats. Was charged for a pump out when many other that had slips received their pump outs for free. Would like to know why!
Marina Response:
There is always a learning curve for staff early in the season. Pump outs are only complimentary for Seasonal Slip Holders and guests purchasing $100 or more in fuel. You did not meet those requirements, so you were charged $5.00 for the pump out. This has been the same policy for more than 5 years. I'm sorry if you were not informed. If you have any other questions, feel free to message us through Dockwa and I will answer your questions. We look forward to seeing you in the future. -Chris Vogel, Marina Supervisorby Mary A. - Verified user on Jun 07, 2026

Thank you M&M! We always enjoy having you stay with us. See you again soon!by Anonymous on May 30, 2026
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.
