Can I stay at a hotel for as long as I want?

Question

If so, do I pay the normal rate or is there a special rate for staying long periods?

Answer 1

I heard the maximum for some hotels is 99 days

Answer 2

If you know how long you want to stay, say like a month, when you make the reservation if the hotel isn't sold out to other people, then yes you can stay as long as you can pay. Some hotels will give a discount rate to long staying or frequent guests.
