Wear it and enjoy yourself, personally I think its kind of a neat idea!! Looks better than a ratty T shirt and ugly sneakers that I have seen people wear to dinner, some people look like they bring two outfits and wear them over and over LOL
This question was raised before, and Randymon's response was that it would be acceptable and welcome.
Two points I would like to make, however. First, I suggest that you wear it on a night when you're planning to eat in an enclosed, air-conditioned restaurant. Otherwise, you might be dressed too warmly.
Second, if you're planning to wear a kilt b/c you want to comply with the "semi-formal" dress code, you should know that the dress code is not semi-formal as the FAQs indicate. In the U.S., "semi-formal" for men means a suit, and there is no suit or jacket requirement for men at any of the Couples Resorts. The dress code, even at its strictest, is casual. If you're planning to wear a kilt simply b/c you like to wear it, however, then by all means, do so.
I know everything, and I'm always right (just ask my husband).
I think you would be fine but you might be a little hot while outside. If you go into the restaurants that are air conditioned you would probably be fine. I tend to get chilly and wear a light sweater in those because they keep them very cold.
I think you would be fine from a dress code stand point but hot! Aren't those things made of wool? I realize you have built in AC but still with the humidity I don't think it would be very comfortable.
