Guilds definatly have their pros & cons. If it is a large one, but has smaller evening groups, you can probably find a great group of people to meet w/& share ideas. I've found SOME can be kinda cliqueish(?), especially in larger cities. I've heard a few negative comments on here about a some.
But that said, I belonged to one many years ago that was great, very supportive, sharing & helpful - this board reminds me of a lot of the ladies in that one. However, it was in a rural area & after moving from there many years ago, I tried a guild in a larger city & found out they were somewhat on the snobbish side & had A LOT of 'quilt police'. Now I don't belong to one.
All are different & you'll never know till you visit one a few times. You may find a group of people who become a 'second family' to you.
Good luck & happy quilting
