Looking for a couple friendly hotel within 8-10k.

My gf and I are in a relationship for the past 3 years. We want to go to a hotel, in the daytime. I dont have any problem booking it for the whole day(thats usually how hotels work ik), however, i can’t go to resorts. Within my budget, is there any hotel recommendations? Also, do the staff ask for marital status, and if so, whats the gameplan. Finally, is it smart to call the hotel beforehand and ask if they allow unmarried couples as long as we provide NIDs before visiting?
