I've run the gamut of tours, from the bike-club-camp-or-stay-in-student-residences to the luxury-hotel-we-can't-do-too-much-for-you tour, and all I can say is you do, to a certain extent, get what you pay for. On a high-end tour the ride leaders will have the authority to spend extra money if they need to to keep the paying customer happy, and they may be more flexible in terms of riding distances or changing the plans. I think I've done 20 tours, probably more. Each one is different.

Having said that, I'm happiest with the small-group mid-price tour where you stay in B+Bs and eat good food rather than the ones with luxury hotels and fancy food. Depending on where someone wants to go, I'm happy to pass on tour company recommendations (or non recommendations) by pm.
