I was wondering if it is still on the cool side during the evenings and if I should be packing an extra cardigan or so (leaving on Friday)? We just returned from the Riu Jalisco on Dec. 11/09 and for the 2 weeks that we were there we had 3 days of rain and it was unusually cool in the evenings. I am hoping that the temps have warmed up and that there hasn't been any more rain. Any help will be appreciated. Thanks.
