I have 2 boys (6 & 4) and we are planning our trip for October. I really don't want to pay an extra $50 per child for a stroller but know that they won't be able to walk the entire time. I know I've read that wagons aren't allowed, and I think I saw that you couldn't ride the train or something at one of the parks with a stroller... anyone have a suggestion? Are there double strollers? What is the price if so? Are there discounts available for stroller rentals? I'm trying to get our budget together so we don't have any unexpected expenses that I could have budgeted for and parking alone is going to be $50!! Any ideas, suggestions, tips ect would be great!
