Due to weather was stranded @ O'Hare. Had a few hrs notice so contacted Diamond Desk. At last minute, Reservation was made using points for Sunday Night. Agent adv he would fax certificate and etc directly to hotel. Gave me all numbers and his name. Arrived about 2230, long line in lobby. Very pleasant lady announcing to us that if no reservations, were sold out, however, anybody with reservations would be accommodated. Partner tried self check in on two machines but neither worked. About that time arrived in front of desk line. Desk agent checked fax, adv could not find documents, however, found reservation, wrote down names, numbers etc and adv would deal with "that" later, just wanted to get us checked in. He was very kind. Presented us with two breakfast coupons and free bottle of water coupon. Room a very nice mini suite. Both had wonderful night sleep . . better than BOS airport and the plane.While one slept, other ordered room service. Was an 1.1/2 hr wait for room service, however, pork chop dinner very good and enough food too. Enjoyed a leisurely and complete breakfast buffet before heading to airport facility. Hotel undergoing construction; did not seem to inconvenience our steps and no noticeable noise.
