Thanks, Andy. Good suggestion, to consider the 70~200 and 1.4X. I agree, I could get the kit into a medium sized bag, along with battery charger, and take my "fanny pack" (or small day bag) to carry the longer zoom and 1.4X with camera and short zoom on my shoulder.
We selected end of April and early May, as we were advised that school wasn't out yet, and there may be less crowds and summer vacationers, but we WILL pack umbrellas. BTW, I have not mastered the "telephoto landscape"....I always seem to be around 24mm to 35mm. I've got to work on that.
Thanks again
Dave
