Are the entrance doors from the outside or indoor?

I'm not 100 percent sure what you're asking. But the check in door is under cover so if it's raining or transporting vampires you should be good. There are also doors from the parking garage door to the 3rd, 4th and 5th floors (although the 5th is an open deck). You may also enter from the beachside and those doors are uncovered.

The room entrances are from the inside

Inside

Inside definitely

Yep.. Inside
