We have three children aged 6,4 and 11 months at time of travel. I am noticing when I search Expedia a lot of resorts are showing as unavailable. I am wondering since our children are so small can I just book as 4? Or do these resorts really not allow 5 in a room regardless of age? I could understand if we had three teenagers but we can all easily fit in a room and the baby won't use any of the food really. If anyone has information on hotels either in cancun or riviera maya that say they won't allow 5 but would permit a baby as the 5th I would love to hear about them!
