Congratulations! My husband and I took a trip in May without out kids and it was fabulous.
The things we enjoyed were:
Visiting Epcot everyday no matter what park we started at. We just enjoy walking around the world...especially at night.
sleeping in when we were tired from staying out late. We took advantage of Evening Magic Hours. MK was open until 1am.
eating at restaurants our kids don't enjoy: San Angel Inn and the restaurant in the French Pavillion.
Took ferry to DTD from OKW.
Enjoyed margharitas while watching fireworks at Epcot.
Happy Hour at the Irish Restaurant at DTD
Each others company. Really did have time to reconnect and enjoy some time in our room which doesn't happen when the kids are travelling with us
free dining and magic express. It was so nice to not have to cook or drive during our visit.
Photopass. It was nice to have someone else take pictures of us. I have a beautiful photo that I have put on a large canvas to commemorate our anniversary trip.
No matter what you choose...you will have a great time because you are going to WDW as a couple!!!!
(PS--we came home and booked a September mini-trip with our kids because while we were at wdw, we recalled so many memories there with our kids that we wanted to experience it again...with them. Hopefully, I won't regret it.)
