The good news is, if your new marriage can survive 2 hour waits in line, multiple times a day, for multiple days, with Disney crowds - it'll survive anything.
Just so the OP knows, you can certainly go to Disney and not wait in lines. We've been the week between XMAS & New Years a couple of times (which is absolute peak crowds), and never waited longer than 15-20 minutes for anything, and many times 10 or less.
We're trying Universal Orlando for the first time ever having only been to Universal Hollywood once for comparison. We enjoyed our day there, but I do remember lines being horrendous, and a 1 hour wait was the norm with no options for a shorter wait.
This upcoming so-called "cheaper" trip to Universal is costing us so much more than any of our Disney trips! The Universal tickets appeared to start off cheap with the 7 day tickets (which we'll go for 4), but by the time we add either a Universal hotel stay or the Express Pass which will absolutely be necessary because it will be a peak week before Easter, the price is about 1/3 higher than our normal Disney trip!
Sorry to go off on a tangent, and I know that there are rather vocal Universal supporters here (as there should be

), but I just had to speak up and state that someone who has done any amount of research at all should not be spending 2 hours in any line at Disney!
We are looking forward to our first Universal Orlando trip, and I'm really trying to tell myself and others in my group not to expect it to be Disney (which we love

). I know it will be different, and different is OK. I just wish we didn't have to spend $365 for a single night's hotel room that we won't even use just to be able to visit the attractions without horrendous wait-times! Disney's free fast-pass is wonderful!
