For fun, we plugged in Boston-Orlando for the first week of December and learned you can go for $723 roundtrip, staying at the beautifully retro Universal Cabana Bay Beach Resort. Since double occupancy is required, the package is really $1,447, which is really pretty decent for six nights plus hotel ($241 a day).
