Just updating...I called CRO this morning and checked to see if the new BEW rate could be applied for our April 2-9 stay at the CR. The agent was very nice and spent quite a bit of time checking to see if the MYW plan would save us money. It ended up coming in a few thousand dollars higher than our room only reservation! I don't think we could eat enough to make it work out, even with two teenage boys! She also said that I should just keep the winter rate (BDP) discount which I used to book the original ressie, since the BEW rate wouldn't save us any money.
Thanks everyone for posting your updates! It never hurts to check anyway!
