If you want tickets, it will become a package and the total would be due now as you are less than 45 days from arrival. A room only cannot be converted to a package as tickets cannot just be added to make it a package. To go from one type of reservation to the other, the first one has to be cancelled/refunded and the new reservation booked, requiring a new deposit (or in your case, payment in full). If the discount you have now is expired, you will have to talk to someone in Guest Services as a CRO CM will not be able to do anything as they do not have access to expired promos. It may take awhile, but Guest Services should be able to help you without you losing the room discount. However, the deposit and any money that has been paid toward the room only reservation will be refunded, with the total amount for the package having to be paid now. Since room only reservations and packages are different reservation systems, money cannot be transferred between the two.
