I am planning our first trip with DD for January 24-27 and have a hotel reserved (Poly) and want to make our ADRs. My question is what is 180+10? I know to call 180 days before we go (we are at 209 right now ) to make the ADRs, but can I call 10 days earlier? 10 days later? I'm so confused. Sorry if this has been asked 1000 times. TIA!
