Also the Crowne Plaza and the Holiday Inn. The Holiday Inn has better location for us (entertainment area vs corporate and train station), many more Hokkaido items at the excellent breakfast, and windows open, so we stay there rather than Crowne Plaza on our annual visits. Our favorite city in Japan to visit. There is also a Mercure. Marriott just opened a Courtyard that has more service than the no complimentary breakfast for anyone Fairfield Inn. Choice also has a budget property.
Park Hyatt will bring the travel complainers, lounge squatters, and selfie takers. and probably high award prices, so I'll likely stick to Holiday Inn and the ideal location and onsen of Dormy Inn PREMIUM Sapporo and linked Dormy Inn Sapporo ANNEX.
Crowne Plaza in Chitose is convenient for the airport and itineraries that bypass going in to Sapporo.
