We have stayed at Caliente several times too - the most recent this past April. Quiet during the week and quite busy on weekends. Lifestylers stay to themselves and activity is most likely on weekend late nights at the upper pool. We were there a week and there was no problem.

There was no evidence of timeshare sales on our most recent trip and we were never approached - not even on check-in. They may be taking a rest until they get further along with the building plans/financing.

You can order and eat food and drinks in the pool area.

Do check the website before you go. You'll want to stay away on a weekend they have a SM theme or big lifestyle bash. There are not often but you do need to check.
