My husband and I are travelling to this hotel on January 14, 2014. We travel every year for the past 7 years. We have never booked a 5 star hotel, always 3.5 to 4.5 in Mexico. My question is dressing for dinner at night. Can my husband wear flip flops and shorts with a short sleeve shirt? So for anyone who has travelled to this hotel, what did you see the other men wearing at night for dinner? I just don't want to have to pack a whole bunch of long pants and dress shoes. Thanks in advance for any help that you can give!!
