More space and access to electricity.
Normally I don't mind not having access to electricity at champ shows despite always using it in the States, but Crufts is the one place where not having it drives me nuts. This probably doesn't bother most people but I hate the idea of bringing a dog in the ring with wrinkled feathering/furnishings from being stuck on a bench all day and if the dog gets caught in the rain when I take them outside for a toilet break I want to be able to dry them properly. We work hard for Crufts all year and it's the one time I do want my dogs looking absolutely perfect. Or even just be able to charge my phone after I've been stuck there all day would be nice.
I don't mind exhibitors coming into the benching area. I keep my dogs in crates on the bench so they can relax and would much rather have them approach me and meet my dogs there/ask questions then do it when I'm about to go in the ring. Some exhibitor and dog-only aisles to the rings and between halls would be lovely, and a ban on spectators standing at the ring entrance.
More ladies' loos is definitely a necessity as well.
