Rhonna, you are referring to the time you can make F! reservations. That is not what the OP is talking about. The OP is talking about when you can talk to Vacation Planning Services as a DLR hotel guest and have them make reservations for F! on your behalf.
MJ is totally correct. Two summers ago we stayed at the GCH and wanted to get F! reservations. However, the 30 day point before our trip we were in Europe and I knew it would be hard to call at 8AM Pacific Time from Europe while we were traveling - I did not even know where exactly we would be or if we would have phone service or be touring something important that day.
So before we left the country I contacted the Disney Vacation Planning services and had them make the F! reservations for me. Not sure how far in advance it was but at least 6 weeks and maybe 8 weeks before we were at DLR.
Just to be clear. The VP services do not make the reservation for you before the nominal 30 day (one month) mark. They put it in their system that you want them to make the reservation for you and then when the day comes, right at 8AM, they make it for you.
Then when we arrived at the GCH they had our F! tickets at the hotel front desk when we checked in.
