First, thank you so much for all of you who post on this forum. I've learned so much from you guys!! In September we'll be on the Wonder heading to the Bahamas. For dinner, I planned on dressing my 4 year old DD in a sundress, light sweater and dress sandals. But now that I've read older posts about how cold it can be, I'm wondering if this is too light of clothes for an average kid?? Any input would be great!! Thanks so much!!
