We were thrilled to find these tent cabins on a beach. I had really wanted to go to Catalina but didn't really want to just do the tourist thing in Avalon the whole time, nor did we want to tent camp the whole time in a campground (at least not in late November, which is when we went). This was a great compromise and alternative. We stayed 3 nights with our family (2 adults, 2 kids ages 8 and 11). The tent cabin is a tent cabin - it was clean enough and mattresses were pretty decent. Woke up to bison grazing outside the tent, and went to bed seeing little foxes scampering around. We had fires in firepits next to the beach two nights, went snorkeling 4 times (saw a turtle, lobsters, and tons of gorgeous fish), kayaked one day, went hiking some (definitely recommend the hike up to the cross, and the headland over the beach on the way to the cross), found little shells on the beach, played board games in the evening, and generally relaxed.
The staff was friendly and fairly helpful overall. Some were very helpful and were super nice about helping us find a wetsuit that fit our son, get some extra neoprene socks for swimming, etc. They were very flexible about allowing us to take out the kayaks and SUPs whenever we liked and not being super strict about timing and cost. It's definitely not a resort, so don't expect service, per se. And the continental breakfast was adequate, but certainly not anything to write home about (cereal, not-too-fresh bagels, pastries some mornings). We brought most of our own food and were happy to be able to use their microwave and toaster to cook (though the power strip would trip off if you tried to use both at once) and refrigerator to keep food cool. The dining hall was a pleasant place to be in the evening to play board games, as the tent cabins are small and have no electricity.
Overall, we really enjoyed our time there and feel very fortunate to have gone. What a gorgeous place to spend a few days, and to have it nearly to ourselves (there was only one other couple there for the days we were there, plus a handful of mostly young staff). The place does have the feel of being on a bit of a shoestring, though - their boat that they used to get us out there had one of its engine's broken and we literally got passed by someone rowing a rowboat. But we got there nonetheless and felt very relaxed doing it, as we got to watch sea lions cavort around us and the staff caught a fish as we motored along. I definitely recommend it to folks who like to get away to quiet places and don't mind roughing it. Oh, and we got a ride back to Avalon from the owner, Annie, who was very accommodating, helpful, friendly, and gave us a mini history lesson of the island as we drove.
