Read a forum post recently (can't find it now to link) where a lady said that she had been asked to change before entering the Sian Ka'an buffet at lunch because of the cover up she was wearing. Don't think she mentioned what she was wearing though. Just thought I would check to see what would be acceptable coverups. To go over my swimmies at lunch I have a casual maxi, a couple of shorter dresses, shorts and some t-shirts. Will these be ok? The shorter dresses are strapless and come a couple of inches above my knee. Thanks! Also are men ok in their swim shorts (not Speedos or anything :)) with a t-shirt? Thanks again - 6 days to go!
