I will be staying in a UK Best Western soon and I am a Diamond member. According to the UK T&Cs
All Best Western RewardsŪ members are eligible to receive a complimentary room upgrade, though complimentary room upgrades are only available at Best Western hotels in Great Britain and are provided at the discretion of the Best Western hotel concerned upon arrival only and are subject to availability.
.
First of all, quite strange ALL members are eligible for a comped upgrade. Would there be any priority for Plat and Diamond?
But it says subject to availability. So if I'd were to check-in and they tell me there is no upgrade available, while when I go online I can still book a higher category room for my entire stay, would they be obliged to give it to me then? So basically, if they are lying about availability for a higher category room, can I push for the upgrade like with SPG?
