I arrived in Amman at around 1:30PM, and my flight out of Amman was the following night/morning at 1:30AM, meaning I had about 36 hours on the ground.
Amman has a few options for Hyatt and Starwood loyalists. There’s the Grand Hyatt, Le Meridien, and Sheraton. While not yet open, there’s also supposed to be a W Amman opening on October 1, 2017, and a St. Regis Amman opening on December 1, 2017.
All the Hyatt and Starwood options were roughly comparably priced, so I ended up booking the Grand Hyatt, given that Tiffany was staying there, as my visit to Amman was overlapping with the tail end of her trip to Jordan.
