I'm not a huge fan of queues as well but we had a good time at DLP even though we spent a bit paying for the fast track or whether it's called.
We're not huge Disney people so while my daughter enjoyed DLP she wasn't interested in queuing up for characters which made my life easier and I realized she enjoyed the thrill rides more hence why were going to Universal for a day this summer.
When my daughter started talking about Disney I wasn't keen but found out about the Disney cruise so we're doing that this summer and spending the week before in Orlando before the cruise.
We're not doing Disney but will spend a day at universal Island or adventure with express, I would rather do one park with express than 2 parks and spend so much time queuing. I'm really looking forward to a day to discovery cove in Orland which looks so amazing and then river tubing and snorkeling in a natural river spring in the Orlando area and drive along a natural reserve where you can see alligators and other animals.
The discovery cove tickets comes with access to SeaWorld and aquatica a water park so we will spend a day each there, want to to go Kennedy space center and then board the shop for a 7 night cruise.
The cruise looks a lot more relaxing then the parks, and I love that they have kids clubs so hoping our daughter makes friends there and we can have some time to ourselves.
Anyway there will be people who regret it and many who love it so you need to decide based on what you like and you and your kids interests, but no it is not compulsory.
