I will be booking our first stay as DVC members soon for a two bedroom. There will be our family and one other family sharing possibly a two bedroom. The second family will be arriving a few days after our check-in would this be a problem? Has anyone else done this before? Also, our family loves the DDP, do both families HAVE to buy the DDP? Does it work the same with the park passes, too? Thanks for the responses....you folks know it all!!
