Attending a photography tour is a great way to develop your photography by learning from a professional photographer in a destination you've dreamed of visiting. Not only that, it's also a great opportunity to connect with other like-minded people and maybe even make friends for life. Some are “photo tours” where they basically take you to a place, deal with the subject of travel, and take you to some places to take pictures. I did one of these with a fairly famous photographer in Greenland.
Supposedly it was a workshop, but I never saw him or his assistants helping anyone with, for example, the settings, even if they were asked. It was worth it, but if I had been fighting technically I would have been very discouraged. If you're a beginner or intermediate photographer, a workshop tour is a wonderful learning experience. If you're more advanced, it may not be worth paying more for classroom instruction.
An educational photo tour may be the best thing for you. Regardless of your ability, a journey that includes group criticism is invaluable. Having the opportunity to see other photographers' images can inspire all kinds of creative ideas. Having a professional criticize your images helps you understand their strengths and weaknesses.
This can take your photography to the next level. One of the best reasons to attend a photography workshop is that you can learn to take better photos. I think investing in experiences is a much better investment than investing in things (such as camera equipment, equipment, etc.).
