Way future cruise question

[LOLA2]

I knew there are only particular dates I want to go and only in cat 3,2 and maybe 1 (depends on cost) so I called and asked the folks at Sisney Cruise what I should do since dates I would like are not out there yet. She told me to fax my info over to a particular fax number. Well I did this about 4 weeks ago. Do I get a confirmation that they recieved or do they just call when that time frame I chose opens up? I just don't want to be waiting all this time to find out they never got my request!!

Can someone who has done this before please tell me what I should be expecting. Thanks
