Many Hilton branded properties (Hilton Garden, Hampton, Embassy, Double Tree etc…) offer day use rooms but you’ll need to book on Hilton.com or their app. They don’t advertise the fact and there is a trick to getting it to work. Not all properties offer them, and it is dependant on demand for a specific day, but many will book in advance so you don’t have to take your chances.
When you’re on their booking page click the day of arrival, then click the same day as a departure date.
They can be a bit more expensive than the day room sites I mentioned above, but in my experience you get the room for longer in many cases. If you’re not sure of your arrival time, or want a longer stay with the girl you’re meeting it’s a good option. Did I say that??? Sorry, a longer time for your business meeting

I’m sure none of us are using these hotels for sex 😇
