Saying that, however, I LOVE going solo to WDW!!!!! There is nothing like the freedom of doing what you want, when you want. Eating where & when you want. Doing an attraction 20 times or skipping it completely. Knowing that the only person you have to make happy on this trip is you.
Now I have heard "won't you be lonely?" or "WDW is for Kids" or "Why would you go alone?" or one of the best one's I've heard is "Going & doing what you want sounds awfully selfish" and so on. My answer to these remarks is always "no I won't be lonely" "No it's not just for kids" "no it's not selfish. When was the last time you only had yourself to please on a vacation? When have you been away and been able to do what you want, when you want? When have you been on vacation knowing that the only one you have to worry about having a good time is yourself?" Those make people stop & think pretty quick.
