Your photos are so pretty! Looking at them, you may want to purchase a couple different kits, and make the pages similiar looks, but using different kits and filling in as needed.
I found some kits that could work for some of the photos you have here (I'm only posting the links because it takes a while and there's quite a few):
https://www.sweetshoppedesigns.com/s...26&cat=&page=4 This one is a black and white, with add on color packs. So you could use the B/W as a base, and then accent colors based on the photos.
https://www.sweetshoppedesigns.com/s...86&cat=&page=4 This one has the pink and blue colors of the last few photos you posted.
https://www.sweetshoppedesigns.com/s...87&cat=&page=5 This one would be really pretty with that last photo (the pink cherry blossoms)

Either of these would work for the more Vegas photos ( you could pull out the themed elements and dress up the pages more too):

Good luck!
