A few things:
-- Aventura. Cool name. Love it.
--This hotel would have some bad views, no? Parking garage for CBBR on one side, and parking garage/convention center on the other side.
--Regarding theme: IF they are going to make this high-end/adults only, I hope they would take a pared down approach to theming. If you're going to spend big bucks, I'd rather stay in a Four Seasons-type of hotel with classic approach to luxury and a focus on service VS. all-out theme park themeing (e.g. indonedian! egyptian!). Just my opinion on that.
