The whole putting up your tent thing is popular now, I kinda shake my head at someone who feels they need to pay someone 300 bucks to put up a tent for them each day, my wife expressed interest and I just shook my head. Its clearly popular but also clearly has the audience of mamby pamby city folks who have money to spend on "being looked after", and an attitude that thinks that putting up and taking down a tent is a hardship.
When I did my first two Cycle Oregons in 2002 and 2005, the tent service was not available. When they added it I couldn't believe someone would pay $400+ for the service, but it fills up in the blink of an eye. Like you, I don't find handling my own tent a hardship. And there are benefits, like being able to choose where you pitch. The tent service tents are grouped together so they are often in a large open space without shade. Also, the tents are often inches from each other. Since you sleep in the same numbered tent each night, if you have a neighbor who is loud and/or snores, you are stuck next to that person for the entire trip. I would much rather be able to have some flexibility as to where my tent gets set up.
On Cycle Oregon, people tout the fact that their bags are delivered to their tents. However, that event has local "sherpas". Usually they are local school students. For a tip (usually $2 or so) they will carry your bag to your tent. A lot cheaper than the tent service, and the money goes to school-related things, like athletic uniforms and class trips. There was some of that going on at the Bon Ton Roulet when I did it last year, only it was the Boy Scouts.
