Hopfully they are not rude, proffesional practise is if any booknig is with a T/A they do the calls and work for information for you, thats why
DCL pays them commsion, it should cut their work as the T/A should be able to cvoer most things.
I personally think the GTY's will not get assigned until just after the 90 day pay up mark.
This isnt anything to worry about just gives DCL the most flexibility in assignment of rooms.
If someone for example has three room requests, on GTY where family would like to be together, they would try to do that, now they know some people will cancel, but they do not know who, so if they assigned a room to you, and the people around you were the ones that cancelled out, you would then block the three room request.
So again it gives them flexibility to move people around on their penciled in lists.
