Yes, you can upgrade your cert category, 30K per category increase. And as long as you have an rewards reservation for the hotel and a matching categories/tiers cert, the agent will attached it.
Hi alc, sorry but just to clarify...what do you mean by: "And as long as you have an rewards reservation for the hotel"--I have to make reservastions first? "and a matching categories/tiers cert, the agent will attached it" What's a matching categories/tiers cert.? I only have the 7 nights 1-5 category cert.
