Thanks a lot everyone for all your useful suggestions! I will be taking for sure: 28-300mm, along with 20mm, tripod, ND and CPL filters. I am not sure about the 150-600mm even though it will give more reach it is heavy and bulky. Instead I might carry 105mm for portrait shots. During this trip I will be both visiting family and doing photography. I am not a professional but an enthusiastic photographer and would like to capture as much as I can. Again thanks for your ideas.
I am fairly certain that there will be a shot or two that you would be able to use the 150-600mm for, but I seriously doubt it will be worth the size, weight, and worry/protection. My previous suggestion to include the 105mm along with the 20mm and 28-300mm was based on your expression for portraits. If the 28-300mm is adequate for portraits, do like the others have suggested and go with only the 20mm and 28-300mm.
