I give couples around 600-900 edited photos in total. The majority of the candids of the guests are individual shots so yes normally as many guest shots as there are guests. These all get uploaded by the clients on Facebook and then social media word of mouth does the rest. Most end up as profile pictures.
I don't have a second shooter. I basically start taking shots of guests after I have taken the room setup shots and don't stop until the first dance. There is always a table waiting to be served or finished their course and waiting for the next. I only sit down for about 10 minutes to eat.
I shoot with the 70-200 and watch people for conversations, moments etc.
Here is a sample
Note these are unedited but it gives you an idea at least.
