soooo, reporting back on Blue Kay in Costa Maya Dec 16-23: we really liked it. :) Yes, it's rustic and basic, but we paid $8 for the taxi for the 4 of us, and $10 per adult, which included a chaise and any 2(!) drinks (got a wristband). Some people didn't pay anything at all, they quietly snuck in and got themselves a lounger each, but they didn't need anything else.   We arrived after 9 and got a place in the shade. Loungers had a soft mattress on them. Not broken up or awful loo
