The way most of the UK auctions work is to have a few days of viewing before the sale itself. Holts generally tend to have Tues, Wed and then Thursday mornings to allow you to view literally everything on sale - Gavin Gardiners is the same. It means you can spend effectively as long as you like viewing the lots, without hassle, and this includes the very best items on sale which is a treat in anyones book. One of my favourite things is to walk around the edges of the viewing hall where there are many cased side-by-sides; you don't know what you are going to find inside until you open the lid
I have not been to the auction day itself, but you can now bid/watch the Holts auction online which is always interesting in itself.
