The Clarion Inn, Frederick has the makings of a top notch hotel. The location is near shopping and plenty of good restaurants. The facility is well constructed with a many rooms surrounding a beautiful indoor pool. If you like off-track sports betting, it has a large lounge area and they are constructing a new front desk. But, they need to spend more money on upgrading the amenities in the rooms. The rooms are clean, but the carpet is cheap, the LED TVs are small, the bathrooms are dated. And most disappointing, the beautiful pool was closed during our visit. If they invest a little more money in amenities, this has the makings of a first class hotel.
