"I've got a place 10 miles west of Phoenix. Small. A few trees with a hammock. Even on the hottest days, I enjoy breezes with that hammock in the shade. I sleep out there some nights as well." - a Hertz bus driver years ago at Phoenix Airport.
I have learned to seek a great night's sleep when traveling - sleeping on a cloud surrounded by fresh air. An airbath. Unfortunately, this is no small challenge.
So many US hotels - old and new - are sealed up tight with terrible air circulation. The room hvac often seems to only recirculate the air in the small space, with no ability to mix fresh air.
I recently stayed at the otherwise pleasant Chloe in New Orleans. "Housed in a 19th-century Uptown mansion", the appeal and location were promising. A local's recommendation sealed the deal for me. We settled in for the evening (temperatures in the low 60's at the time) and I attempted to open a window and enjoy the beautiful air. Not a chance. The 2020 LeBlanc + Smith mansion renovation apparently sealed the beautiful old windows and closed the upper deck.
The limited air circulation lead to poor sleeping conditions.
Similarly, Galveston's Grand Galvez - located on the Gulf of Mexico (!) - also features sealed windows. Guests cannot enjoy the superb breezes.
