I’d plan your holiday around the parks/places you think your kids will enjoy the most. If they are into the bigger thrill rides then definitely go to Universal. Disney is amazing and is magical and fun at all ages.
As a bare minimum I’d suggest you need 2 days at Magic Kingdom and 1 day at each of the other 3. It’s nice to spread it out over more time though if you get say a 14 day ticket (they are very good value for money compared to the shorter length tickets). Combined with a villa you can do things like a park in the morning then chill around the pool in the afternoon or pop to the outlets/mall. A bit less intense than doing the full day at the park “trying to squeeze everything in” type visits.
We love Universal and definitely advise booking a night at one of the hotels that includes the express passes. It’s absolutely great value for money that way and makes it a lot more enjoyable. They’re virtual reality/3d style rides are out of this world also. You get nothing anywhere close to being as good as them in the UK.
Kennedy Centre is about an hour drive away and also an amazing day out for older kids.
Gatorland is nearby and a fun, less tiring day if you’re into that kind of thing. Although on our last visit (we’ve been 4 times) we drove down to the Wild Florida gator park and also booked an airboat ride on the lakes which was absolutely amazing. Really highly recommend it if you can squeeze it in!
We always hire a car and normally a villa as we like to escape from the madness of the parks sometimes (as much as we love them!). But the last visit we did do 2 weeks at the Old Key West disney hotel which was amazing and did feel like a totally different experience. You do feel a lot more emersed in it all and, although we had a car, we used the internal buses to travel from the hotel to the parks so saved on parking costs. We were just across the water from Disney Springs too and they had a little boat you could hop on there and back which was really magical and fun (Disney Springs is a large outdoor complex of shops/restaurants/cinema/bowling/cirque de soleil etc). We did say though that we would book a villa again when we went back as, as ‘magical’ as it was we did feel a bit disneyed out by the end of it and the villas you can get out there are great value for money and a lot more space to spread out 🙂
It is the type of holiday that takes a lot of planning the more you want to do but I find that part of the fun of it all (my husband just asks me what we are doing everyday and where to drive! 😅).
Gutted with Covid, would have definitely gone with the kids now they are teens in the past couple of years. Although, for the first time we have booked California for this summer for a change and will be visiting Disney there too!
Absolutely love Florida, it is the best holiday, you’ll have an amazing time ❤️
