Here is another thought for you since no one else has suggested it.

Cruise prices drop in January, and cruises are pretty much all inclusive. There are some extras how many is up to you. Also, some cruise lines have great children's programs. Our granddaughter had ball on Royal Caribbean.

If you do decide on a cruise do not try to book it yourself. It can get complicated. (Learned that the hard way). Make sure you use someone like Bonnie Buchanan who specializes in cruises, or a travel agent who is certified as a cruise agent and had lots of experience.
