I would want to be there, I think.

uggh. my husband sees no reason to set our schedule back a week, but to me this seems like a huge thing and, the way things have gone, i feel like i need to monitor.
i'll call my builder and see if i can make this happen.

I would definitely wait until I came back. Brick suppliers are notorious for sending out multiple lot runs of brick for 1 job. There can be huge color variation between lots that you may not notice until you're looking at a giant expanse of wall. We had 3 different lot#s show up in our shipment--only 1 was the same as the brick they had already put down for the foundation. I noticed it and brought it to the GC's attention. The brick supplier apologized and brought out more brick in the correct lot. Our framer was working on a gorgeous house in the town I work in that had a brick lot problem--beautiful large Georgian-Federalist style house. There was a definite line that ran across the front of the house about 2/3 of the way up where you could clearly see a different lot of brick was used--the options were to tear down the wall and start over, live with it as-is, or paint the brick. They now have a beautiful very large Georgian-Federalist style home in a pale yellow color.

I would want to be there for sure. We had stone and not brick, but we did have him change some of the color variances. They had 3 different colors for the window sill--looked like a checkerboard. We changed it to 1 color--liked it much better. This was changed while the mortar was still wet which was much easier than later.

You should definitely be there. We had to have brick removed and replaced twice.
