"Sprint's Marriott code SPR is a telecom code. Sprint (now part of T-Mobile) had major HQ in Overland Park KS. Properties near that corridor still encounter Sprint-branded employees during the merger transition. hotelcorporatecodes.com lists SPR with "⚠️ Sometimes" verification. Telecom codes are in the medium-enforcement tier — more commonly audited than retail, less than consulting/finance. No SPR-specific denial incident found in public forums."

"My last couple of corporate RFID cards had no company name on them for security purposes. My current company doesn’t do business cards. I use my Bonvoy card for corporate travel to get the points. I’d have to write them an email standing at the check in desk, I guess."

"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."
