I went to Long Beach a few years ago for the 5 day MEI/CFII. The only had 1-2 planes and 2 instructors. We had a problem with the airplane while I was there, and both instructors had to take the afternoon to fly it to Vegas and trade it out for another one. If you have a good reason to go to Long Beach then it will be okay, but if I had it to do over again, I'd go to somewhere that ad a bigger office -- like Vegas. As a side note, Vegas usually has better weather. My check ride had to be rescheduled due to bad weather, a common problem with coastal California.
