I think 90 minutes is the ideal amount of time for a full body massage. It gives me enough time to stretch out and do a thorough job. One hour is fine but it’s a little tight getting everything done for a full body massage. Two hours is great, especially for people looking to escape the world for a while and reduce stress but it’s a bit too long for others. Unlike many spas, with me you get the full amount of time. I don’t take 10 minutes off for changing in and out of clothes. I give myself 30 minutes between massages so there’s time to finish the full massage even if it gets started 10 or 15 minutes.
