Looking at wildlife tours in Teton National Park NOT Yellowstone for December. There are several companies listed in Jackson that do these tours. Need to know which one is best for seeing wildlife and photography. Gray line Tours and Wildlife Safaris are the 2 that seem to fit what we are looking for and are the ones most mentioned. Are there any others that would be better? Which of these 2 would be best? We are 2 older adults looking to do this type of tour without breaking the bank. They offer half day or full day tours. Which should we consider to see the most wildlife and NP area?
