I used ALLA last month and loved every minute of it. She provides everything through email and we had no issues. I do wish we had splurged for a group of 4 or less though. No waiting at any of the sites with the really small groups. We had a group of 16 and it was fine, but would do the small group in the future. Such an intense 2 days... every little thing that eases your time is worth it!
Good luck and enjoy!
