2. We had a sleepover party at Susan's house.

(Which expression is correct? Are both grammatical?)

Q2: Do only girls have a sleepover? How about boys? Do they have sleepover parties? Do all teenagers have sleepover party in the USA?
Ms. Sue
Both are correct, but 1. is more common.

Boys also have sleepovers. I don't know about ALL teenagers, but certainly most have sleepover parties.
