Baby shower length

Kinda stressing out because we’re having a mixed shower, and about 50 people are coming. We weren’t expecting everyone to confirm and only reserved the room for enough time for decorating, a 2h shower and clean up. Everyone said it was enough time and now that the numbers have been confirmed people are saying we wont have time to open gifts without rushing.

I’m scared people are gonna think it was a gift grab when in reality we were expecting a lot less people and everyone said to make it short because they don’t like long showers.

I don’t know what to do. HELPPP
