The vibe is great, very inviting. The pool is nice, could be a tad bigger or the deep end filled in since it’s very small and not really used. Definitely will be back.

Upon first glance one might get the urge to quickly drive past the establishment but once you enter you will be glad you did. Though the place is a little outdated and could use some updating it has a lot of character and very inviting. Definitely worth a night, or 3...;)

Wonderful visit

This was our second visit but the first time staying overnight. We loved it. The room was clean and the king bed was very comfortable. Our AC could have been a little cooler but wo cares! We were naked the whole time! We just lounged around the pool and enjoyed each other. If we wanted privacy we would move to other areas around the property. The playrooms were clean and other couples were respectful. There were only couples or female employees present so it felt safe and balanced. We would definitely come back!

Needs lots of updating

The place is in a weird neighborhood. It all needs a facelift. In my opinion it’s very overpriced. Whomever did the pictures for the website needs a raise because they make it look very different than it is (in a photoshopped, nice & new sort of way). The toilet in my room didn’t flush properly and I asked for someone to come look at it. No one ever came. The hot water also didn’t work in my shower. The staff was all friendly & the pool was nice & warm. Went as a single lady & all other couples were respectful & it was fun to be able to be naked & just enjoy the sunshine.

Really disappointed in the service from the girls. They couldn’t even tell people when food got delivered. They stayed in the office 90% of the time. We really didn’t appreciate the music at 2am when everybody is in their rooms sleeping and I couldn’t even hear our tv. Ear plugs did nothing. Also it is advertised as clothing optional but that is not the case at all. Just disappointed to spend that much money on mediocre service, crappy stale food and a jacuzzi that was not that warm and needed water added. Music was also not good. Overall just a ok experience, we won’t be back.

SMI is a unique resort in that you truly feel at home. You can bring your own food and alcohol and sit around the pool all day with your favorite drink. They provide good music, snack foods, ice, mixers and pool towels. Need anything? Just ask and they are happy to provide it. The rooms are clean and very close to all the activities, so don't expect a quiet library setting. Expect a pool party and you won't be disappointed.

This was our second time visiting. Sea Mountain is a nice little getaway to relax and recharge. Rooms are clean and comfortable, pool is nice and warm and the staff are friendly and helpful. If you’re expecting a full service resort then this isn’t for you. Its a little pricey if you want a room and it could definitely use a facelift and some TLC but if you want a nice spot to kick back for a day or two then I recommend swinging by for a little sun.

Great place to get over a tan! Had a little bit of adult playtime! Comfortable setting with a nice pool and a hot tub. The "Goddesses" that work there are very friendly and welcoming. they provide some food, but limited actual dining spots... eat on the pool lounge chairs.. there are restraunts nearby, but who wants to get dressed to go out when the sun is shining. We had a good relaxing time overall. Went to town for dinners. They do provide lots of apples, cookies, crackers and chips as snacks. make sure you are there on a saturday.. many added events ( lingerie fashion show)snacks, lunch and drinks.
