We will be checking into ASM late on Thursday night (probably 12 midnight to 2 AM0 for one night, room only. Then on Friday morning checking into POP with a package for 2 nights (Night of Joy quick trip). Will my AMS room be held since we are going to be late? Can we get our tickets and hit a park on Friday morning? I don't expect our room to be ready but everything can stay in the car. What is your experience doing this?
