So, I have reached my 180 day mark and I've been making reservations for ADRs. The system will only allow me to do one day at a time as that day gets to 180days. It won't let me book any further. We are staying at the wilderness lodge and this shows on MDE. We are booking from the UK through Virgin holidays if that might make a difference? I thought I should be able to do 10 days in advance after the booking got to 180 days. It's not too much of a problem apart from having to go online every day to book a new reservation.
