I think the scenario mentioned above regarding FPs across the board but onsite guests get an extra is an interesting take.
Right now I'm a bit sad because I need to coordinate FPs with a friend who is NOT staying with us but visiting for a day;her window won't open for another 2 weeks (and I'm really not sure if we can add her for a single day to our reservation...and if the extra fee will be worth it). The FP that the BF and I were able to book for 7DMT on that day no longer has openings during that time, so we'll have to redo that FP once my friend's 30 days hits. Hopefully there will still be slots. Hopefully my friend will have purchased her ticket and linked it to
MDE by then as well!
Also, although I'm staying on site, I didn't get the 180+10 advantage for ADRs either because I booked a couple weeks past that. I didn't realize onsite guests got extra time - I actually started making reservations day by day at 180 days out before I even booked the trip to guarantee we'd have something during the general time frame we were going (we were contemplating 10 days of 3 overlapping weeks).
