travel recommendation?

hi, I turn 60 this year and my wife has graciously said she'll send me on a photo tour like an African Safari, trip to the Galapagos, or other photo destination. So I'm looking for you well traveled types to help me out here. venues as well as specific tour companies etc... I don't need luxurious accommodations, but do want good guides, tours, etc... She suggested a Nat. Geo. tour, any thoughts and help welcome.

thanks, Tom D

What are you most interested in seeing? and how much physical activity do you want (or can take) on your trip?

My wife and I just returned from a tour to Peru and Machu Picchu sponsored by AHI International. It was fabulous if you like to photograph archaeological sites and people. If you want to photograph wild animals, this would not be the tour for you. Also, the high altitudes (up to 13,000 feet) did cause shortness of breath.

I would say mostly wildlife, landscape as well, and other cultures. I can complain with the best of em about discomfort, but can handle a lot( I was a waterfowl hunter in younger years), so I can take lots of discomfort to accomplish a goal. so I don't care about top shelf hotels and such.
