We are booked for the 4 night cruise in May, cat. 10 staterooms. I am a family of five, we have connected rooms with my SIL, a family of 3. It is set up that our 1 1/2 year old is rooming with my SIL, making us each a family of 4. Here is the potential problem...My SIL is in the process of adopting and there is a very small chance that my niece could come home before the cruise (which would be absolutely wonderful). Would we be forced to up grade to a family suite, if there is one even available? Or can my 1 1/2 year old sleep in a crib in the stateroom we already have booked? That would mean 2 adults, 2 kids and a baby in a cat. 10! HELP!
