Thus you would have the opportunity to either decline the upgrade and/or ask for a different one if available. And if the check-in person came back with there not being any double available, that is where the Room Type Guarantee would come in to play.
I defer to your judgement, we don't know what type of hotel this was. I've seen lower than FS charge extra for double beds but not the opposite.
Just something not making sense here as if they were running out of needed doubles and wanted to see who would accept without saying anything and who would complain...
