Why are we assuming these promos stack?
It said it clearly in the first link, I believe. "Also, get a $75 Visa GC" or something like that.
Certainly seems to imply they're stackable, although terms seem to explicitly say otherwise.
The terms also say "unless otherwise specified". It seems it was otherwise specified.
Does the person who checks in have to be on the card (if I put their name on the reservation)?
They definitely need to pay using the card.
