OP here again, and another thank you for all the replies! This has given me a huge amount to think about.
I totally understand that most people, especially in the US, don’t get enough vacation leave from work to make this feasible. It’s certainly a nice problem to have, I will admit - this is a “big” vacation for us, celebrating a round-number birthday for both of us. We do usually go overseas for 4 weeks at a time, but I really have no idea what to expect at WDW, so I’m not sure how overwhelmed we will be.
We had not planned to go to Universal, purely because my husband has epilepsy and so many of the rides have seizure warnings. I saw a
YouTube video about the Orlando Eye complex and that looks fun - additionally, there seems to be transport to Legoland from there. I’m also very interested in the manatees! As mentioned, my husband would like to go to NASA. It does sound like we can do most of these without a car, but I maybe shouldn’t be quite so adamant that I won’t hire a car.
@Tiki_Sara, thank you so much for the info about driving in the US - that’s great to hear!
@tucky, this will be my first trip too, so I’m not sure how much use I can be. I will say that we have 2 friends coming to meet us, both for 5 days, and I think we can make it work so that they will see and do plenty. I do know that we were told that the hotels are filling up quickly for October, but obviously we were looking for a lot longer than you. Table service reservations can be made 180 days in advance, but if you don’t care about that then you don’t need to worry. It does seem that you will have the best time if you do a little bit of planning, even if it’s just picking your FastPass options so that you can go on some of the headliner attractions. I lurked on this forum for several months before I joined recently, and there are lots of people who really get a lot of pleasure out of the planning, but there have been threads about how little planning can you get away with. Touring Plans has a good planning checklist, and there is lots of info on this site, both in the articles and on the forums. I don’t think you need to have a rigid minute-by-minute plan, but spending a little time becoming familiar with the basics might be helpful. Good luck - I hope you have an amazing trip!
