This is great news. Not sure RSSC is the one at fault, sounds like Travelocity, especially given how unhelpful they've been to you. But RSSC stepping in and resolving it really shows the type of company they are. I'm glad to hear you are booked and I'll keep my fingers crossed for you on the vacation issue.
By the way, you will LOVE that trip. We did it last May and enjoyed every second.
