Question about DDP and Paying

[LynnTH]

Oops - Duplicate Pose....I am renting DVC Points (have done this before). We are on the DDP and it is added to our reservation and we pay for this when we check in. Here is my question. I know that changes to the DDP have to be done 72 hours in advance. Right now it is me, DH and DD and DS going. My DH will not know if he can go until maybe not until the day before. It all depends on the spring flooding here (he works at a Marina) and they are expecting major flooding. If that happens he will not be able to go. If he cannot go - will they still charge me for 4 people when we check in? We hope to know more in advance but not sure at this point as we can't control Mother Nature.
