You shouldn't have any problem on November 13th or 14th. They are the Monday and Tuesday after the Veterans Day holiday, so everybody should be going back to work and the kids are still in school. Typically Mondays and Tuesdays are the quietest days in the park.
If your parents are elderly, you might want to get to the park at opening time when the crowds are really down and then go back in the early evening after a nap. Then come back for dinner and evening. Check the park hours, however.
Another thing you might want to consider is staying at one of the Disney hotels. We prefer the Disneyland Hotel. It's easy to get to. You can take the monorail [I think it will be open then] and then you don't have to wait for the buses in front of the park.
HEY FreshTressa -- sorry to interrupt -- i've been trying to PM you and your account isnt' accepting any due to being full can you PM me once you've had a chance to clear it out a bit? thanks!
Well, if you run into my family who will also be down there the same Tues & Weds (and also Thurs), you may encounter a very loud and sometimes unruly 2 year old "princess", otherwise, I've heard that it hopefully won't be too bad.
