It is very diffrent going on a photo trip with a tour company as opposed to a specially designed trip for photographers only. E.g. You get up early in the morning (depending on the season, but can be as early as 4.30 am) travel to some place nice to take sunrise shots, followed by early morning shooting to take advantage of the soft lighting conditions. When the light becomes too harsh, like about 11am - 3 pm, you may travel to another spot during this downtime to shoot more subjects. Or you might travel to a different town where you spend enough time to take sunset shots. After dinner then you may be driven back to your hotel at about 9.30 - 10 pm. This is a typical day's routine.
With a tour company, the tour guides will bring you shopping or to some tourist spot where they will collect commission s from the stuff that you buy. You typically leave the hotel at about 8.30 am, which doesn't give you time to so sunrise shots. You'll be lucky to get 2 - 3 hours of good shooting time in a day!
So it all depends on what you want to achieve when you go on a trip.. To sight see or to take photos! I know what I want!
