I called with a PIN code and tried to book 2 rooms. My DH, DD and I for one, and my parents for the other. First CM said,no can do...explained that we had traveled previously as a group...etc.... Thanked him for his time and hung up. Called 5 minutes later, got a delightful woman named Mandy, who merrily booked the two rooms for me.
So, don't know. Is the plan to allow only one room and the booking CM's are just learning that? Dunno. Was I successful because the first call I used my husband's last name, and the second time I used my own which is the same as my parents, the other party? I don't know. But I am pleased as anything to book both rooms for 40% off!!!!
But, to those told no to more than one room, call and talk to someone else!! You might get lucky!!!!
