My understanding is that MDE is a two-way street. If you enable yourself to see their plans, they can see yours (and book stuff). However, you don't have to worry about your group messing up a stack by booking something. You build a stack by booking a new G+ LL as soon as possible when you are eligible. If you book immediately when eligible, your group members will never be able to book a G+ LL for you. If it happens that they book a G+ LL before you do when eligibility comes up, this is not a problem as it will NOT break a stack for you as they would have built a stack for you. You can cancel what they did and make a new G+ LL reservation*. The exception would be if a LL got converted to 'anytime.' I don't know what would happen in that case, but I've read that 'anytime' passes can break a stack.So Question #1) When we are booking G+ LL, can we have everyone's tickets linked in my account so I can make reservations for the group but unselect them if they are not with us BUT not let them book anything for us (ie we are not booked in their account)?
However, they could mess with your plans by deleting something you didn't want deleted, but that seems less likely.
Since FoP ILL$ is paid for separately, it gives you the option to select a time. Booking as soon as possible (7AM if staying on property, park open if not), will give you the most times to select from. In other words, you don't have to 'time' your booking since you can pick from a list.Question #3) What time (if at all) are FOP $ILL's selling out? I expect BIL/SIL will need to utilize that if they want to ride it, so I want to at least give them a reasonable window they have to wake up by.
On a busy day, FoP can sell out in the morning (11 November data shows it sold out around 9:30, with sporadic reappearances later in the day). On less busy days it doesn't sell out as fast, and since you want later in the day anyway, you would be in good shape; but booking sooner will give you the most choices.
