I am a solo parent traveling on the Dream with my 2 boys ages 8 & 10. I'm budgeting for airfare, transportation to the cruise, tips and a $250 in fun money. I'm curious if it is possible to have a great DCL cruise on a budget (i.e. no port adventures, limited additional expenses). Is Castaway Cay doable without additional expenses? Can we have just "fun in the sun"? I don't want (or like) to skrimp but its that or no cruise.
