I'm so glad you asked, IT WAS THE WORST TRAVEL EXPERIENCE OF MY 68 YEARS.
I have travelled all my life. My first language was Japanese (1947-1949). My second language was English (1949-1953). My third language was German (1953-1956). My fourth language (relearning English) obtains to this day. In the meantime, I have learned Greek and Spanish, to facilitate my constant world travels. Although my law offices are in Spokane, Wa., I have lived most of each of the past 15 years in my home in Belize, C.A. Needless to say, I have stayed in countless hotels, around the world, and USA. I understand that my wife has been using Booking .com recently. I recognize that my wife booked (online) our 8/15 2am-9am as an 8/15-8/16 room, when it probably should have been an 8/14-8/15 room.
Here's my problem: When we arrived at the Ramada at 2am on the 15th, the front desk person (a middle aged male w/ a high-pitched female voice, which my wife recognized immediately) said that the hotel was full, citing rules saying that a 2am-9am should be booked for the day before. Apparently, this Ramada is one of the few hotels I have encountered, which does not save an emergency room.
The reason my wife recognized the rather unique (trust me...) voice is that, upon my request, she called the hotel directly, confirmed our date and times, confirmed pet/smoking rules, and inquired about shuttle service from the airport. He advised(presumably w/ the reservation on screen) that the shuttle did not run at that hour, and that we would need a cab ($25), which we ultimately employed.No discrepancies were mentioned. (interestingly, for any readers, the "two miles from the airport" website claim is deceptive. It is two miles from the dedicated land at the end of runways, but about 12 miles from the terminal.)
Your records should reflect that my wife had overlapping reservations at the airport Marriott.
