Do hotels generally allows check-in?

Hi guys. I'm going to see U2 in concert in Seattle next summer. Recently I booked two nights at a hotel outside of Qwest Field. I can fly in and fly June 19 June 21 20 June is the day of the concert stage and I will do all general admission day. I have a few hits on the day before the concert. So I will fly early morning and arrive in Seattle early in the afternoon. It is a hotel allows guests to check In the first, in this case? If I can not check my hotel early Where I can keep my luggage, so you can visit without having to carry anything around me?

Hello, I am only 14 so I know But I ID the same as saying .. we were in the same hotel on same cause Im going too! WOOOO
