What do you need to deliver on Monday, the best of the best (say 20-30 photos) or all of them?
Either way, I would be going through them every evening, but if I needed to deliver them all I might even try to download and if possible, go through them as I have downtime throughout the weekend.
I find it valuable to do this anyway as it gives you a chance to see what is working and what is not so that you can make any adjustments the next day.
If you are using Lightroom you might want to create an import preset for this event with any adjustment that is fairly universal. I will often create a starting point that has the highlights pulled down a bit, the shadows raised a bit, clarity up a bit, sharpening to the range I normally use and lens correction turned on. I find this saves me a lot of clicking when I get to my keepers, especially if the lighting and exposures are fairly consistent.
You may also like to add a little contrast and/or saturation, etc. anything that you end up doing to most every picture anyway. You can also add metadata to every picture with a preset.
I find I need every extra second when working a job like yours and a preset can help a lot.
