It was absolutely great going solo -- just different than going with family or friends. Dining solo was what I was the most nervous about, but in the end, it didn't really matter. Other diners were so into themselves that they didn't notice me, and the service I received was excellent.
For me, the best thing was just going with the flow. I think I hit 3 parks in one day, but I also found that because I was solo, I pushed myself more in the parks than usual. Usually, I have my son with me to slow things down and I found myself on the go more often than not.
I guess my advice would be to take time to yourself (not the parks) and relax!
