So I leave this Friday with my family to Disney World. I have been debating on weather or not I should bring my 70-200 f28 IS lens with me. I am not really going sightseeing. I have no problem bringing it onto the plane, it is carrying it all day in a place that probably has a very high rate of stealing. Of course I will be sure to be by it at all times though. I wont leave it at the hotel unless I get it locked simply cause I dont want it to go missing. I am torn on this cause I dont know if I really would need it but if we end up going someplace that is a show type thing (like the Shamoo show at sea world) I will wish I had it. I will have my 18-200 lens which I really hate but for now it is what I have, so I iwll have the reach, I just wont have the sweetness of high quality glass.
