I think it sounds like we'll be there at the same time - the week before Easter. This is also our first Universal trip after many Disney trips. My only Universal experience is with the one in Hollywood, CA and we experienced very long lines during the Summer, and I don't want to repeat that experience in FL. And I do think lines will easily be in excess of an hour during that very busy Spring Break time.
Here's what we're doing. We're planning on 4 days total at Universal during the week. The first and last day we'll arrive by 8:30 and will do attractions through about lunch time and then eat a nice lunch. I expect things will be quite crowded and lines will be unmanageable at that time, so we'll probably leave and take a break. We're staying in an off-site condo. We've reserved a room for one night in the middle of our trip at Royal Pacific Resort at Universal which will give us 2 days with FOTL access to the rides. These will be the 2 days where we do the rides as often as we want to. The price is high, and we won't even sleep in the room, but it was cheaper than 2 days of 2-park express passes. The cheapest room was at RPR for $324 + tax for a total of $364. 2 days of 2-park express passes for 4 people would be $436, so it's cheaper to get the hotel room. We actually have 6 people, so we'll get 5 room keys for FOTL, and then will buy Express passes for the 2 days for the 6th person. The 6th person will not be doing the big rides and we figure we'll be find with only doing the shows and attractions once that all 6 in the group would be doing. But the 5 in our group and re-ride the big rides on those 2 days. If it's warm enough, we might bring our swimsuits and take a break one of the days at the resort pool. We might even go see our room and rumple the beds or something just to say we got some use out of the room!
So, I'd recommend thinking about splurging on one night at a Universal hotel even if you don't sleep there to get 2 days of FOTL access. We figure we'll use our first day to sort of scout things out and find out way around so that when we do have FOTL access, we can use it more effectively. Our last day will be one last chance (in the morning) to repeat everyone's favorites.
I hope this helps!
