We are planning our second trip to DL and would prefer to use our Marriott Reward points. We stayed at the Fairfield last time with great results. We are going to have an extra adult with us this time, though, and the free breakfast at Residence Inn is enticing. Do the roomier rooms and breakfast out weigh the convenience of the Fairfield? We are flying so we will not have a car to drive back and forth and will depend on our feet. A 6 and 9 year old will be with us. Has anyone stayed at the Residence Inn. How far is the walk?
