No! No! and No! Don't worry about a thing. They come in all shapes, sizes, nationalities and walks of life. My dh and I sat each night in the bar a watched the line ups of the ones that "didn't want to miss dinner so they lined up an hour before the dining room opened." What did they think - someone was going to give the food away?
We only noticed how varied the outfits were - even on formal nights their were jeans and t-shirts and cut-offs and halter tops along with formals and tuxes. We honestly could not tell you what one individual actually looked like - except maybe the guy on formal night in his daisy dukes (yes really), cropped t-shirt and cowboy hat! If you dress like that people will stare lol. Go, enjoy, be comfortable and happy. We also took note of the sourpusses - the ones that would not have a good time no matter what. They were the funniest. Have a great cruise and if we are on the same ship - come and join us! TTFN Jennifer
