I know this isn't much to go on, but it seems like production has recently chosen finales in cities that have either never been visited or have only been visited once. New Orleans in 32, Detroit in 31, San Francisco in 30, Chicago in 29, Dallas in 26. I think it might be reasonable to expect something similar from 33. Given that filming will be in winter, I think we can rule out cities with cold weather - Minneapolis, Boston, etc. Maybe we could expect something along the lines of San Diego, Houston, Austin, San Antonio, Tampa, Jacksonville or Charlotte? Or if the stick with a 'usual' state, maybe they could spice it up; if they end in Hawaii maybe they could visit an island we've never seen or have seen only once (Lanai, Kauai, Big Island, etc) instead of the typical Honolulu finish line. If they insist on ending in the greater Los Angeles area maybe they could go to a new part of it - maybe coastal Orange County, Malibu, Oxnard or the Channel Islands!
