Ask HN: Subscription based Vacation/Travel

First time asker here. I work/slog throughout the year even during Summer and don't plan or take vacation. Sometimes its due to financial constraints, but most times its due to poor planning on my part. A thought came to mind about subscription based vacation site. You can deposit money throughout the year and then 2-3 times a year plan a vacation. Create a playlist of vacations. Googling around I found Masterpiecerentals which offered this model but since has been flipped over to luxury vacation rentals. Anyone know of such websites? Any comments on this business model?
