Keep in mind Grand Colorado is a deeded week resort with an internal points overlay program for nightly stays at Grand Colorado.The points mentioned can be used for internal reservations, I believe starting at 6 months from the desired reservation date. To date we have never converted to points. Grand Colorado can be a member of Club Interval, which is II points exchange program. We tried that once and found it to be a horrible value vs the standard weeks exchange. Plus Club Interval membership is more expensive than just plain old II weeks membership.
Our summer value week exchanges well. But a spring/fall week is very much off season. I’m not certain how well those weeks exchange. On the plus side the studio suite has a separate bedroom and sitting area and it trades as a 1 bedroom unit with II, so no upgrade fee to get a 1 bedroom exchange.
