Some of the things I learned on my first bike tour:
1) SPD pedals (specifically mine) make PERFECT beer bottle openers.
2) Spend a few extra bucks on a good tent, it's worth it.
3) If you can't enjoy the ride, at least enjoy the company.
4) Never underestimate how chilly it can get at night or in the morning dew.
5) When ending for the day, setup your tent, lay out anything wet and go right into the shower.
6) Did I mention SPD pedals make great beer bottle openers?
7) Bring a CO2 inflation system, it really does make a difference when you get that one flat near the very end of the day/ride
8) Spend a few extra bucks on a good pump, it's worth it.
9) Don't pack your panniers full, pack them mostly full so you can carry group/shared gear.
10) Get an inflatable mattress/therm-a-rest.
11) Do laundry every night you can (as a group).
12) NEVER think of yourself as an island. Everything you do in a group tour effects everyone else.
13) Really, SPD pedals make amazing beer bottle openers.
