Going to Vegas---->Grand Canyon---->Sedona or Scottsdale for a week of relaxation with some light activity (hiking, biking, shopping) in a spa like atmosphere?

Going with my husband, 21 year old son and 72 year old mother.

We have the Vegas/Canyon portion of the trip locked up (activity wise anyway) so…

Suggestions for either Sedona and Scottsdale? This will be the end of the trip so we want to be able to wind down and meander around one of these areas. Want to get a 2bd TS or Bed and Breakfast. Anyone have thoughts on which area would be yes? We will be there the 2nd week in MAY.

Thanks
