Disneyland when I'm 35 weeks pregnant?

So... in November all of my family, and extended family have planned a trip to go to Disneyland. I'll be 35 weeks pregnant, now although I know rides are out of the question, I'm more concerned about being on my feet and walking around all day from sun up, to sun down. I'm pretty fit, and I have been staying moderately active through out my pregnancy, but I'm wondering is this trip gonna be miserable? Am I gonna have a tough time standing and walking for that long?
