PH Beijing
A few weeks ago, I stayed at the PH Beijing and was chatting with the Front Desk and she said each night, there is a list to prioritize the Globalist for Suite upgrades (as this hotel has limited suites) compared to the GH Beijing (where I get upgraded all the time every stay).
She wasn’t sure of the exact criteria, but she thinks it’s based 1) how often the guest staying at THIS hotel
2) type of room booked (by rate)
3) Lifetime Globalist vs normal Globalist
