Here is an idea to keep your hotel bill down if you are staying more than one night. Check each day's rate individually and make multiple reservations if they are different.
For example, if you are staying in a hotel from Friday night to Sunday night, the Sunday night rate may be measurably lower. So you might want to make one reservation for Friday and Saturday (if the rate is the same) and another one for Sunday. On the other hand, if you say you are arriving on Friday night for three nights, you might get the higher rate for all three nights. (Different hotels may or not not do this.) The author of the article below suggests telling the hotel what you are doing to prevent being moved to a different room for the subsequent reservation.
