Is the 17-55 long enough or do you find yourself changing lenses.
Conversly does the 24-105 go wide enough for those group shots?
My other lens is the 70-200 2.8 IS but I want to keep lens changes to a minnimum.
Both great lenses. Either carry two bodies, or switch lenses.
17-55 f/2.8 is wide enough, but not long enough to do a whole event on a APS-C body, unless it is leisurely, or you crop. Get the 17-55 and a front belt lens pouch to swap 70-200.
24-105 is wide enough AND long enough on a 1-DMkII body or 5D, but not on a APS-C body. These bodies, this lens, and a flash can do a whole event, as long as you are not into selective focus narrow depth of field shots. It needs a flash to help focus in low light, being f/4.
Carry a step ladder. Then you can use the longer lens more over the heads of people to zero in and pick out subjects without people blocking, and without out having to get in their face with 17mm.
It's a toss-up call with one APS-C body. I have used both lenses. Both make excellent images. I busted my 24-105L focus ring already and had to have it fixed. I don't like where the manual focus ring is on the 17-55mm - opposite position to L lenses - but I have not busted that plastic lens yet.
Maybe get the 24-105 AND a Tokina 17mm f/3.5 for in-close, wide shots, or big groups and tables.
You can do a whole event with those 2, with a flash and higher ISO. The 17mm in the pocket is certainly more portable than the 70-200 in pocket. And image quality little concern on the wide stuff anyway.
I do not like using wider than 20mm focal length on APS-C sensor for groups because perspective distortion near frame edges stretches peoples' facial features. So, the 24-105L IS and a Sigma 20mm f/2.8 would do a whole event also.
Only you can decide what you like to do.
