I know they say reservations can be made 180 days in advance. Do I need to figure out exactly what 180 days is? Or, for example, if I want to make a reservation for Christmas day (December 25) will I be able to do that on June 25th, which might not necessarily be exactly 180 days in advance. I hope I'm making sense! Thanks!

The reservations can be made 180 days, not necessarily six months. So I believe (double check this) you wouldn't be able to make a reservation until June 28th. June 28th would be 180 days from Dec. 25th. HTH
