Called a few places to make last minute booking, and they all say that their reservation team is not working today.
So what happen is, most hotels reservation agents do not work on Sunday, and the voucher expires on Sunday, and it doesn't work on any online travel agency booking sites, only work at the hotel directly.
Essentially the voucher expires on Friday 5pm.
What is so stupid about this?
Call and ask to speak to front desk, they normally can assist with a booking.
