Officially - No.Can we use GV for staying??
Like can we use 25% off benefit and pay using GV??
You'll be advised to book at Standard Rate and then use the GV
Unofficially - Yes.
If you have some bit of Inroom Dining or Restaurant Charges billed to your room then at checkout you can give the GV. The balance post deducting food charges will be used for off setting your room night charges automatically.
Done it enough times , never been a problem
