Answer 1

would be full

...... ........

Answer 2

The receptionist informed us that the hotel was full.

In this sentence, the verb "be" is in the past tense ("was"). The receptionist is giving information about the hotel's current state at the time the statement was made. The use of the past tense indicates that the hotel had already reached its maximum capacity and did not have any available rooms at that moment.
