At 2 he's not going to get as much out of a vacation as he will later on... like 5 and older. So I say save your $ for trips to kid parks later (Disney will cost you at least $3k, so save, save, save for later).
At two he'll have fun anywhere you take him as long as you play with him.
With that said, look for a hotel/location that's good for you and your hubby AND has kid activities/sitting.
Go to the Holiday Inn website and find hotels with kid suites, some will have kid activities too. Then pick a location that suits you and your husband.
Whatever you do, go cheap. I have 3 teens and you cannot save enough money to fill their teen-desires. Trust me!
It's not where you go, but what you do together. Playing and having fun.
