I got an email for an Advantage hotel promotion to get "up to 10,000" bonus miles for hotel stays booked on their site, check out by November 15th. There is very little information, and it's confusing how miles are earned/calculated.

After 3 stays, you're supposed to get 3,000 bonus miles per stay, "up to 10,000 miles". So does that mean for the next FOUR stays, you would get 10,000 miles, seven stays total? These are "bonus miles", which are in addition to the regular miles you're supposed to get, but the math doesn't add up to me. Why not say "earn 10,000 miles for the next four stays"? Are they being misleading, or am I reading too much into this?
