It is on holidays that the vast majority of our pictures are taken. How many people actually set out to take pictures other than while on holiday, or at a camera club function ? I do sometimes, but not as often as I should. So, on this basis, some camera gear goes on holiday. Many years ago, when the kids came along, I stopped trying to take all of my gear on holiday abroad. For example, a trip to Disney in Florida needed some photographic gear. For the family, we took a video camera and my wife's zoom compact with PLENTY of colour print film. For 'serious' work, I took my Canon EOS 600, with it's 35/135 and 100/300 USM zooms. The Canon 300TL flash, meant for a T90, went too. I had filters and hoods on each lens, and a polarising filter. Spare batteries - not so important in America as they are plentiful and cheap, and a portable darkroom - a changing bag in case of jams. I set the camera so that it didn't wind the film fully back into the cassette, and this allowed me to change from slide to mono mid roll if I wished. If you do this, ALWAYS wind completed films back FULLY into the cassette when used to prevent accidental re-loading. Any unfinished film should have the number of frames used written on it's leader as soon as it is unloaded. I carry a felt tip pen for the purpose. Reloading a part used film is easy. Load normally, then put the lens cap on, set the camera to 'MANUAL' the fastest shutter speed and the smallest aperture and wind the film to 1 FRAME PASSED THE NUMBER WRITTEN ON THE LEADER - then you can take pictures again. When on that holiday, look for the unusual viewpoints, and subject mater, not just the usual tourist shots. Out of the way places can be very productive, but watch the security. I must admit to cramming as much of my gear as I can into the car boot when holidaying in this country.
