Just got back last week although we flew.
Couple of thoughts
1) found the Disney fast pass pretty hard to use, times we wanted and rides we wanted always booked. ( lot of that may just be us, and an inability to use it, but did find it hard to use)
2) universal does it different, you pay them an extra $80 per person, bumps you to the fast line, money well spent in my opinion.
3) Mears taxi is Ok but spendy, use Uber, works much better.
4) parking, if you drive to the park, is going to be $20 plus per day, and you will be out in the north 40, a long way from the gate. Where as uber will drop you right at the gate.
5) SeaWorld is the least crowded, and we did enjoy it. The Dolphin encounter for $45 is fun
6) just getting into the park, is not like back in the day. Now it is much more getting on a Airplane, bag checks, body metal detectors, scanners
5) traffic is heavy, and I found their freeways, confusing, another reason not to drive to the parks.
6) June will be even more crowed than 2 weeks ago, which I found bad enough, Just saying, although it is fun and worth doing, Disney is a hard vacation
