Newbie: Should I get wide-angle for fall foliage trip to Blu

[samoca]

Am leaving 10/23 for Asheville, N.C.in the Blue Ridge Mountains. Am a Californian, sothe chance to getgorgeous fall foliage shots is a rarity in my life. Have been using a CanonS-400 for the last couple of years and have been happy enough but this trip seems to me to warrant an upgrade. I do like the smaller size of the Panasonic. Is it as good a camera overall as the SD800? Or should I get an SD700 and not worry about the wide angle (have read that it's better made than the SD800)? Please help, I have to decide quick!!! Thanks.
