[The Truman Show]In a way, the entire giant Dome is Truman's house. Can a vampire enter the Dome without being invited? And if so, can anyone besides Truman invite him?

No, a vampire can enter the dome without permission from Truman. It would need permission to enter his home however. This is due to the fact that the entire dome is actually a public use area, just because the people living there are actors doesn't give ownership to the one idiot who isn't an actor. 

Vampires can enter hotels and such under similar allowance, these places aren't able to be sanctified like a private home would be.

For example Angel and Spike  from Buffy TV series can enter hotel rooms freely even if not invited. Furthermore Peter Vincent in the remake of Fright Night, purchased the penthouse he lived in specifically so that vamps couldn't enter it, as they could if he had just rented it.

The folklore justification for this is probably the fact that many homes would have a private family shrine or small religious display, where as public place other then a church wouldn't have any holy symbols.
