Trust me when I tell you that you have not experianced Walt Disney World until you do it sans children. I have been with my kids and my grandkids (I'm 65, wife is 64) multiple times. Starting 5 years ago my wife and I decided to do it alone, no kids. Halfway through the week my wife exclaimed that this was the best time she had ever had here and couldn't understand why. I too was thinking the same thing. Then it came to me, no kids. What I would suggest is this, pick a park for the morning, enjoy yourself, have lunch, take your time. Go back to the resort for some pool and rest time. Slow down. Enjoy yourself. Have fun. Then, head back to the park (I always get the park hopper so we do 2 parks every day) have dinner and enoy the night time festivities. Here is the best advice I can give you. You are so used to bypassing what the kids didn't want to see, standing in line for what the kids wanted to see, rushing back and forth with your fast passes, you never really took the time to look at things. Slow down and really look around you. We have been going alone now for 6 visits and we still find things we have never seen or done. You will just have to get used to the fact that you are enjoying these parks like never before. 137 more days and we're back.
