Wow - a girl goes to work in the morning and a lot happens before lunch
Here's my 2 cents on the whole thing (ok well those that know me know it will be more than 2 cents worth).
#1 - this is something they have been talking about for a while. When we were on the last Member Cruise and talking to the DVC reps in the suite they mentioned wanting to do something to attract new cruisers. There were about 6-8 of us standing around talking (not all DISers) and we all said that attracting new people was fine but we didn't want to be excluded. One suggestion brought up was to have two cruises. A 4-day for new cruisers and a 7 day for veterans.
#2 - DVC does read here and DVC does listen to what its members say. In the same discussion listed above we talked about port options and it was mentioned that CC, sea day, CC would be a great cruise. Looked what happened! (and no I don't think it came out of that one conversation

).
#3 - the phone system is a bit of a lottery but one that doesn't work very well. The problem is the phone system is set up to be efficient 364 days of the year and that one day is always going to be a problem. Anyone who has tried to get hot concert tickets, World Series tickets, etc. knows what I'm talking about.
#4 - I could be wrong. Those of you who have been in DVC longer than I have can answer this. Didn't they used to have a lottery for the holiday weeks? You put your name on a list and you were called if chosen? Might not be the best choice but might be the most fair if they can't book two cruises.
#5 - while I agree that it appears that the DVC cruisers are timed badly for those with school age children they are still very successful. Member Homecoming which was planned for a more family friendly time wasn't as big a success (of course this is apples to oranges but you get my drift).
I would hope that DVC would do some kind of survey before making changes. Finding out if people wanted to book and either couldn't or didn't. If they couldn't - why? Bad phone lines, bad day for calling, etc. If they didn't - why? Too many points, bad time of year, etc. I really hope we wouldn't be excluded from future DVC Member events but if the rules change and we don't make it we'll find other ways to use our Membership for that time and try again.
