Just peeped into the Marriott-Centerpoint in Pontiac/Auburn Hills. M-Lounge is right off the lobby, keyed access (was guested in by someone staying who talked his way into getting keyed access--midafternoon there were gummy bears/raisinets and soda/water that I saw (unstaffed). Were there for a much-delayed (since 2020) event and it seemed a perfectly standard suburban office park Marriott. Across the street was a Courtyard/Residence Inn (not sure if they were a combo or separate) which some of the event participants used. Seemed remodeled in the last 5-ish years (I was concerned that it would be like the former Hyatt in Dearborn...terminally dwindling, but the Marriott was fine and fresh). Only weirdness was that there didn't seem much of a dress code for the employees (though it was extraordinarily hot/humid this week; a little grace is due, I'd say. Net-net: perfectly fine office-park Marriott, rather isolated from anything interesting.
