Fishbone -
I manually compiled my own list of the prices for a 7 day cruise using the
DCL online quote system over a period of about 2 weeks. Yep, it was a long and tedious job, but I was curious about it and I worked away it for about 20 minutes per evening. I started working on it in early September of 2001. The prices may be different now, but the price trends would still hold true.
I made my list for a category 6 cabin for 2 adults for the calendar year of 2002 and I put it into an Excel 97 spreadsheet.
If you have Excel ver 97 or above and would like a copy of it, I can email it to you (or anyone else that's interested), just let me know. I'll be out of town on 2/7 and 2/8, but after that would be fine.
I can tell you from memory that under normal pricing, the lowest prices are the first 5 weeks of the year (excluding Jan 1), and then the weeks in September, October, and November. Any week with a Holiday throws it off.
