First timer & I could use some help please!

[KristeeS]

I'm a single mom to one 12 year old girl and I was invited to go to WDW in Feb! Holy Cow! Neither one of us has ever been so I'm SO EXCITED!! (I'm going to surprise her last minute, so shhhhhh! lol) This is such a last minute trip for me but I want to be as prepared as possible!

Here's the deal (so far, this is all I know): We're going with a group of families. (I only know one family but I'm sure we'll have a blast!) We're starting off with 2 days at Universal Studios and then 6 days at WDW. We're staying at The Mermaid (?) in Disney. The rooms, meal plan, and tickets are all already paid for.

What else should I expect? Do I have to book anything in advance? She's too old for some of the more kiddie things, so what can a 12 year old expect? Most importantly, which boards will have the most helpful info for me?

Thank you all so much!
