Welcome to our forum.
I just got back from wet testing the Caldera Geneva. I floated a little in the lounger but the rest of the spa was great!The corner seat has a headrest that surrounds your neck and keeps you seated. It was very comfortable.The other seats were also nice and the built in raised foot well is an addition that all spas should have (IMHO) it helps keep you seated and also gives people their own place for their feet. I really like it.I feel the need to wet test the HS again just to make sure.
Drober - great assesment - we were debating between the HS Vista and the Geneva and went with the Geneva for the same reasons you are concerned about. Definitly wet test them both again - jsut to make sure. (we went back twice )So far We love the spa and have no complaints. I do have one suggestions for Caldera - the second panel on the Utopia versions is not backlit and it should be....cant see the bottons very well in the dark.
At night we wear our stealth suits, no lights, no clothes, no float unless you want to.
