Check-In Times?

Hi everyone,

I will be checking-in to the Hanpton Inn Tropicana In Las Vegas for a night and my flight lands at LAS at 8pm.

I also will be checking-in to the Hampton Inn Downtown San Diego for a night and my flight lands at SAN at 7pm.

For these hotels is a late check-in ok? I guess for Las Vegas I'll get to the hotel 8:45pm ish and for San Diego 7:45pm ish. Will this be fine?
