3 weeks?!?

I'm lucky to have a free trip to Disney World this summer, so my husband suggested we extend the trip and do a hotel tour. So we'd be staying at 6 resorts in 20 days. Last night I was elated, I thought it was a great idea. We decided on this rather than a beach stay since my son said he wouldn't go into the ocean. However, today I'm freaking out at a 20 day vacation at Disney World. We are able to do it, but I'm worried it's just a loooong time. We would only have tickets to the parks for 6 days so the rest of the time would be exploring the resorts and Disney Springs. We aren't renting a car so we'd stay in the bubble the entire time. Is this crazy? Are we crazy? This seems crazy.

I'm editing to add this:

We're staying a total of 20 days. We have park tickets for 7 days. We check into 6 resorts but because we won't get in until after 4pm the first night, we'll get 5 free water tickets. My kids are obsessed with water parks right now so we'll go every day. That's 11 park days and 9 full resort days ending at the Polynesian for 3 nights.

The more comments I'm reading, the more comfortable I am with the length of our trip. Oh, it's crazy all right. To go to Disney World for almost a month?!? What in the Toontown?? Fortunately, cost is not an issue and we will have plenty to do. My husband always packs so I never have that stress (he prefers to pack). Work is still a bit of a worry, but not too much.

I think it's going to be great, and we can always Uber or rent a car to go out of the bubble of we really wanted to. I think it's totally nuts, and maybe tomorrow I'll doubt this plan again, but I think for now, I'm excited for this trip!
