To their credit they've made B84 somewhat tolerable in recent times. Especially with the elimination of the bus boarding area, at least you're not blasted with the heat every time the doors open in the summer, and only one giant Sam's Club fan to cool down the holding cell.
It sounds from the published reports in the Chron that it's more of a renovation, and less of a knock it down and start from scratch that I'd hoped for.
If the Marriott does go, I hope any future airport hotel takes a cue from the Westin Detroit Airport at NW's terminal. Simply the finest airport hotel in North America with access to the terminal.
It'd be nice to see any future IAH airport hotel have a close direct link on the CO Terminal Link monorail, vs the "It's a Small World," train outside security and below the airport.
