DH and I love Road Scholar trips and I pipe up whenever I see them mentioned on ER. We have been on three trips, all US. Our next one is San Francisco in September.
We feel they are a great value. Wonderful experiences. We did not take a RS trip during 2014 and I am sorry. So far, we have done Red Sox spring training in Ft. Myers, San Antonio and GA islands. Each of those was an incredible experience.
Usually, we just go someplace and plan our on itinerary and have a wonderful time. RS trips throw in so much more than you would probably ever get on your own. Hope we get the chance to go on many, many more. Highly recommend RS. (Know nothing about Costco).
