Does anyone have any experience with CWT Vacation Club membership (Carlson Wagonlit Travel)?

With my RBC Infinite Avion I consistently get promotions from CWT and I'm curious if there are any benefits to joining and using them as my primary travel agent for vacations? For example, they claim I can use my RBC points to book stays at Sandals resorts, (with additional bonus points earned as well) although I can't find conversion rates anywhere without signing up. I doubt the redemption rates will be better than flight rewards, but thought I'd see if anyone has anything good/bad to say about CWT.
