I stayed at the Marriott in Dover over the weekend for a quick trip. I had absolutely no issues with anything at this hotel. All of the staff were very professional. The room was clean, had a mini-fridge, a microwave, and was easy to keep at the desired temperature. The pool was pretty small but is heated and there is a tiny (maybe 4 person) hot tub. The fitness center has dumbells, treadmills with installed televisions, and at least one other machine. The "business center" in the lobby was like it is in most hotels-- a computer off in a separate corner. The breakfast was very good-- eggs, toast, bagels, coffee, juice, etc.
The hotel is very close to Dover Downs Casino, Dover International Speedway, many good restaurants and downtown Dover. There is a liquor store across the street (13).
Overall, this hotel was very relaxing. But I'd hate to see how it is packed on race weekend in Dover.More
