I take DD (3.5) all the time by ourselves. We have AP's to Disney and Sea World as well, but I'm not going to renew the Sea World passes until she's older (whenever we go there, we end up leaving after a couple of hours and going over to Disney...I guess it's just not for us).
We usually go once every week or two for a day trip. DH rarely comes along, he only likes to go if we are staying overnight.
We have a great time every time, neither of us could think of anywhere else to spend mom/daughter time.
You said you are moving to GA...I think we would die of withdrawal!
