If you are new to Universal I think you would enjoy staying onsite and realize that you get some very nice accomadations for your money compared to Disney. You can get express pass for staying at RPR, PBH, HRH. Cabana Bay is the budget friendly resort and is very nice. It does not give you express pass ,but you get early admission as do all onsite guest to all the resorts.
You did not say how long you were going to be in Orlando.
I take my grandchildren to Universal every year since they were young. There are plenty of things for you and your children to do including WWOHP.
If you are going during peak times express pass is important.
In Hogsmeade there is Forbidden Journey, flight of Hippogriff, and dueling dragons. Fight of Hippogriff is a small coaster parents and kids can ride. Then there is Three Broomsticks to eat at and there are shops. Also if you have not read about it there are interactive wands that you can buy for your children to do magic at different areas in Hogsmeade and Diagonal Alley. The map with the interactive spell sites is included with your wand.
Also you want to have park to park tickets to ride the Hogwarts Express back and forth between the two Potter Parks.
The experience is different in both directions.
You need to see the Ollivanders wand show at Diagonal Alley..they pick children out of the audience for this show. Then maybe lunch at the Leaky Cauldren. Just walking around and seeing all the shops and doing the interactive wand spells as will as wandering through Knockturn Alley is something to see. I would suggest you go to Universal site and wander thru everything on there. It is really helpful
At Universal there is Minions, Shrek, ET, Woody WoodPeckers Kid zone. There are the characters Simpsons, Scooby Doo, Transformers and Shrek they can get pictures with and more. They also have the Beetle Juice show.
At IOA there is of course Hogsmeade but they would also love Suess Landing. This particular area of the park is all about the kids and they love it.
You would be suprised at the fun you all could have there. my suggestion stay on site, get park to park passes for three days and have a blast at your on speed. Then head back to Disney if you want. You will not regret it. Have fun
