we've taken the kids 6 times in the last 3 yrs, so when we talked about going for a short 4 day getaway with just the 2 of us last sept., we felt NO guilt whatsoever- we couldn't WAIT to take advantage of evening EMHs, sit-down dining, pleasure island, etc.
we got the hotel reservations, air travel tickets, babysitting all lined up, and we were all set to go, and then.......................................................................................................NOTHING. i just COULDN'T do it....i couldn't go away for that long, so far away, and not to WDW where we have SO MANY wonderful memories as a family (i was worried i wouldn't be able to enjoy it there, where i couldn't help but think about the kids!).
we cancelled the reservations, and have the airline ticket money left in the system (to make things even more convoluted, i wanted dh and i to fly separately, so we have $ in the system for 2 different airlines).
we're planning on visiting my parents in tampa this jan. and we're hoping to get over to WDW, just dh and i, for a day or 2 , and then perhaps taking the kids over there for a day...hopefully THIS plan will work out!
good luck with whatever you decide,
