Stroller rental...single or double

My kids are 4 1/2, 8 and 9 1/2. Should I rent a single or double stroller? Is it better to have a double incase one of the older ones get super tired and grumpy, or is it too much of a hassle to fold it up to go on buses, boats etc.? We are staying at the Swan and Dolphin for 8 nights over spring break and plan to do all the parks…

I would probably get a double just in case one of the older kids gets tired. I can see my 8 year old taking advantage of a stroller. Plus you can use the extra space to put stuff.

Are you renting at the park? If so, you can rent for one day, then at the end of the day or the next day convert that rental to a multi day rental with the discount (just keep your receipt). That would allow you to test the double stroller for a day.
