I just checked the cost of a room at T-rump Hotel in Washington D.C. for two adults and one 5yr. old child...$748 per night.
This room features 480sq. feet with 2 queen beds, room for up to 4 additional guests (up to 3 children) with cribs available. Book for 3 nights or more and receive up to a 25% discount! Soap and toothbrushes available. Breakfast available for a mere $40/night/person.
