Yeah! :dance We're also a family of four!! How old are your kids? Our oldest son will be 14.5 yrs. and our youngest son will be just turning 12. This will be our 7th RCI cruise and our kids' 10th cruise all together, the others being on Princess and Carnival.
You're in for a treat with the Voyager Class ships! We went on the Adventure in 2002 and we were surprised at how easy it was to get around even though it was so huge. We found our favorite place to hang out every night (Promenade Cafe) and during the day, went rollerblading and ice skating but missed the rock wall.
Are you flying into MIA early?
