Hotel hacks could earn you a free upgrade instead of paying for an upgraded room
We don’t get asked to upgrade our rooms every day. Many would love to upgrade their room, but it may come with a price. The hotel may want to earn as much as possible from the night.
You may also find that your hotel oversold the room you requested and it is not available despite what was promised. You may find that they will upgrade you for free if this is the case. We’ll at least be in the same room that we booked.
