this kind of thing very subjective one lah... we didn't know that u were carrying video camera and tripod and we have no idea what you will be shooting, how you will be using your gear and what is your shooting style.
if this is a casual family holiday, i would suggest you travel light... carrying all that gear is gonna give u nightmares and you will be a walking target for thieves with a video camera, DSLR and expensive lenses.
if i had to choose, for a casual holiday, i would just bring the 18-55. but that's just me cos i normally shoot close and i don't like superzooms.
As felix and others said, kits and 50-200 is enuf, cos if too many lens, its cumbersome and heavy having to carry those lens aound when u travel. I would suppose its travel and casual holiday and u want to have fun and excitement. Travel light.....
If I am going for birding or specific macro trips, then those tripod, monopod and many other accesories is neeeded for that specific trip, including different focal lenss, spares battery and many back-up. cos its a photographic trip mainly for that purpose.
Dun break your back over it... especially if you are traveling with family.
Kit + Short Tele is nice enough. Others will be extra.
95% of my US trip shots were with the Tamron 17-50mm f2.8... mostly the usual group, scenery and some street shorts.
