Just a little clarity on how the hotels work. On the $300 pp credit or the one night pre hotel night there are no options to select your hotel.

Usually one hotel (Standard suites) one hotel (premium suites)or if only ONE hotel the premium guests get an upgrade.

Once a hotel fills with the block Regent takes they often change hotels for additional guests, both for the standard and premium guests. The reservationist who answer the phones can ONLY see the current hotel being offered. So the would not know (unless they just remembered and that would be unlikely with all the bookings and hotels all over the world) if any other hotel had ever been offered.

Often if you are concerned about the hotel you are staying in it is better to do your own hotel. Usually hotels can offer a transfers service (for a fee of course) from the airport to the hotel and call a taxi or organize a transfer for the hotel to ship transfer.
