Christmas Day Crowds at USF & IOA?

[GSLand]

After reading about the large crowds at WDW on Christmas day I'm wondering what to expect at USF and IOA? Really crowded too?
Staying at HR and we are so looking forward to FOTL!!! This is our first visit to Universal; mom, dad, teen daughter.
Any Christmas day advice for us newbies?

Thanks.

christmas day shoudn't be overly busy, but should be busy nonetheless. it's the days following, up to and including New Year's Eve that it's PACKED. even with your FOTL, you'll have some wait.
