We've been there when the temp is high 60's and it's great.........our kids have gone swimming (they're young adults). Our kids say the pools are heated and while you don't stay in the pool for several hours, it okay to spend some time in the pool and then get out and head back to the room. Now.......we were there in early January (daytime temps were 48/52 and overnight temps were high 20's/low 30's)......way too cold for pool .........lifeguards were not even working.............signs on the pools stating pools were open, but, swin at your own risk. As far as parks in high 60 temps........it's great.........no humidity, usually no lines, locals avoid like the plague since it's too cold..........for those of us from the north.......high 60's is perfect!!!!
