"I work as a consultant and frequently ask for and use my client's rates (at their insistence, since I will be billing them back). I have been asked for ID maybe one time in 15 since February, when it was announced in this forum that rates would be ID'ed."

"I wanted a higher room floor at a Seattle area hotel. I requested it at the front desk when checking in. The front desk thanked me for being a platinum member and told me that the hotel is fully booked and no “upgrades” to a higher floor for me. The girl behind me checked in and she was thanked for being gold, and they gave her a free upgrade to a suite and let her choose which room she wanted! I asked about the upgrade and they told me it’s random. I spoke to the manager and the manager said lots of rooms available and she gave me 5 rooms to choose from. 🤷🏻‍♂️ In the end, I got my upgrade. Had to fight for it."
