We were on AC in April and my hubby and I walked from VH up to town and hopped into pools all along the way. We didn't get told no by anyone (but then again we didn't ask) and bought Belikins at each place. I think it depends on your demeanor too- if you're loud and obnoxious you probably won't be well received- we are mellow and unobtrusive so we might have just slipped by. I wouldn't try to get in the pool at VH unless you're a guest there tho. Have fun- if all else fails you can always walk to the end of Ramon's pier and go in- just don't jump off the end (we got in trouble for that one!) the water is GORGEOUS and there's not much sea grass near the palapa.
