This is a test of preposition use. 'Check into' is the correct formation when the meaning is 'register at'-- They checked into (= registered at) the hotel last night.

Hi, Mister Micawber

deviating from the main idea of this question a little bit, is it also possible to choose "checked"?
Like they (the police officers) checked the hotel late last night for any criminal activity going on

Thanks !

[Mister Micawber]

.
Sure.
