Hi! Since no one has answered you, I will tell you what I am planning to do. I will be on the May 12 trip. For the theater night, I plan to take a pair of black knit exercise pants. They are loose, relaxed fit and will not look like exercise pants, hopefully. I plan to pack a couple of dressy tops to go with them. I will pack capris and maybe jeans, depending on the weather that week, for day time wear. I will pack nice tops that look more cleaned up in case we won't be going back to the hotel to change before dinners. I expect that whatever we wear all day will be our evening wear also with theater night being the exception. I am planning shoes that are able to do a LOT of walking.
I went on the Italy trip and really stressed about clothes. I discovered that everyone wore regular casual clothes and athletic shoes and we all looked like tourists together!
I hope someone who has been there will help with more advice!
