My first cruise leaves in 18 days (3 night Bahamian on the Dream- so excited!) and I've been scrolling through Google for tips. I've seen a lot of people recommend that you keep bathing suits and first days necessities in a carry on bag, but I was wondering if DCL has a size limit? I don't trust airlines with my bags so I prefer to just pack light and carry on everything, and since I'll be leaving for the airport after school, I'll have everything I need in a bigger-than-normal backpack (http://store.apple.com/us/product/HC681VC/A/herschel-supply-co-little-america-backpack?) as well as a purse. Will I be ok bringing both items on the ship as carry on or will they make me check the backpack? Thanks!
