So I've never booked a bounce back offer before, but we're heading to Disney next week and I'm thinking maybe this time I will. Does anyone know what the current offer is and for how long it extends? We're thinking of going back Dec 2018. What if I don't know what resort I want yet? I noticed that the discounts are tiered so if I book a value resort at x percent off and then if I change it to a deluxe in three months, does the discount update, stay the same or disappear entirely?
