I have read a number of posts were people ask what camera/lens combination should they bring to Disney or on other vacations. After each trip I bring my DSLR and compliment of lenses (In this case the 7D, 10-22mm, 24-70, and 70-200.) I am happy I made the effort.
It is a pain to carry around...plus anyone with you or around you will think you are nuts lugging all the heavy equipment around but the results are well worth it. (Especially those holding/watching it while you enjoy some of the rides.)
I have to finish sorting through 1500 pictures but here are a couple of my favorites so far. As I joke with my family....Memories fade, pictures are forever. (As long as you have proper backups and good ink/paper.)
I just thought I would share my thoughts for anyone contemplating only bringing a point and shoot on vacation.
