Why are they sold on CR?? You can always book a wing room....much cheaper than the tower, but still fairly pricey.... there are tons of very kid fun places to stay that are much more budget friendly....don't break the bank because they think that is the only place to stay...figure out what the budget is....see what your on site options are and let them pick from those and don't feel bad about it....because once they are there they won't have any regrets no matter where they are!!
Doesn't look terribly promising for codes this year, but you can always watch and hope.
