My 30th and Scarlett's 2nd birthday celebrations

I decided, with the help of no one, that for my 30th birthday I would like to take a vacation. Not a weekend to the beach but I want to fly somewhere that I may need to use my passport. That said...my choices were narrowed down to Puerto Rico (by going here I would visit family and also take my mother with me so she could watch the baby if we want a date night), Costa Rica (beautiful country with lots to do) or a Disney Cruise (I love disney and I think Scarlett would too). So far I'm still debating...I really need to make up my mind before October!
