I attend a World War II event in Cedar Rapids every year, and last year I had gone for a drink at the bar at the Double Tree Cedar Rapids which was a very nice place, so I booked a room in it for this year's stay hoping it was equally as nice.
Arrival
I drove south down I-380 past the speed trap cameras and to the downtown exit. The streets around the hotel are kind of a mess, and I would have been better served taking the 7th Street exit when coming from the north.
The Room
Since this is a convention hotel and I believe designed for a lot of occupancy, there weren't a lot of options for upgrades, especially with my son bunking there too. Rooms with two beds in a suite are fairly non-existent.
The Restaurant
350, the top floor restaurant and bar is pretty nice. The food for breakfast was hotel standard, pancakes, omelets, American breakfast, French toast. The items I have come to expect. The dinner was a little more imaginative but I had to have wings, because... yeah, wings!
There is a pantry/market place where you can buy snacks, toiletries, ice cream, soda. A mini-convenience store.
Facilities
They have a gym with two rooms and a pool on the third floor by the conference rooms.
Being attached to the main convention and event space in Cedar Rapids, I feel it was mostly geared towards that. They do have their own event spaces, lots of smaller rooms, and the ballroom on the top floor.
Summary
I believe this is the best hotel in town. The bar is the real awesome spot in this one. The rooms are not bad, just nothing super special either. It's really the spot to be on evenings when an event is going on at the Power House event center.
