Enjoy your alone time at the parks! If you go with a great attitude and a mental plan of what you would like to do, you can maximize your time and have fun! Do some of the things that you may not be able to do with others. Enjoy the shows on the streets at DCA and sit and people watch. Last year when hubby was sitting on a bench there, Donna and 'Lady' sat with him and they chatted. he loved it. Of course, if there are rides you love, you can also take advantage of the single rider lines. When I was there alone, I did my favorite rides (met some cool people on GRR, too) and then took in some of the sites that I usually don't have time to stop and enjoy with others. Have a great time.
