Anyone been to HP at Universal with kids and want to give me some tips??

We are just starting to plan a trip for my oldest’s 10th bday. She is OBSESSED with HP and we’re planning 3 days in the park. I think she will want to repeat some things but more than that I don’t want to feel like we have to rush since we’ll have a 3 year old too (and a 7 year old - he likes HP but we’ll also hit up some other things at Universal). I’m thinking we’ll aim for early in the park, come back to nap etc, go back later in the day.

Our plan is to stay on property to get the perks from that. Probably end of January or maybe early February.

Any tips welcome, for kids or adults!
