went to IOA on Friday 5/10 and Universal Saturday 5/11 and both parks on Sunday 5/12. I saved these parks for the week-end since I was staying onsite and had front of the line access. With this, crowd control is irrelevant.
I was able to go to the Disney parks sun, mon, tue, wen when I thought these would not be so busy.
The new hotel at Universal is opening in June, and I heard they had great openig specials, like $99 a night with a fun card, or an entertainment card would get you a discount at any of the hotels on property.
Regardless, they have a fast pass system and if you have a multi-day ticket, you can get fast passes.
