We got a 2006 Sienna in March & love, love love it! The prices are very reasonable for what you get, barely more than the used ones we looked at.
Friends have a mazda mpv, and it is nice, but not as smooth and not as large (good/bad depending on your needs).
We also have a Honda Accord 2000, and have had several major problems (transmission, car's computer) but Honda has been great! They fixed 3 issues out of warranty.
One reason we chose the Sienna without even looking at the Odyssey is that we tow a pop up with it. Because the Odyssey has a history of transmission problems, and towing is hard on the transmission, we preferred the Toyota.

I managed to get a decent price by requesting quotes from a number of dealers via email and telephone. Anyone who is looking could probably get a great deal in another month or so, but I was afraid I wouldn't be able to get exactly what I wanted if I waited too long.
...last year we were all cramped into our jeep liberty for 12 hours.
Let me put in my vote for the Chrysler T&C. We have a 2004 Suburban right now, but if I could get my T&C back, I would do it in a milisecond! It rode great, and after looking at many minivans we found that it had the most room in the third row seat. Also, there is tons of cargo room, at least in the long wheel base.
I know stupid reason.
. Everybody else was not hurt at all.
At first I was not happy when dh told me I HAD to get the Sienna, but I was with him at a company meeting when they mentioned the "new" Sienna coming out in a month. I looked it up online and was thrilled and have been thrilled since! I have the Limited all wheel drive. Great van!
