I think coming back at a less busy time is a little bit unreasonable as far as the Santa line. If you have time off on a weekday or are a SAHM(D), weekdays are wonderful, especially early in the season, but if you're trying to work around work and going as a family, you're likely stuck with evenings and weekends, and as the season trudges on, a Santa without a line is not possible, even on weekdays. Most families, you can guess 2-3-4 kids. I would be upset if I suddenly found myself behind a gaggle of 10 or if Ms. B's entire kindergarten class made an appearance, but I haven't run into any situations where the number of invisible children is that off the grid. They typically have all the kids get a picture as a group and quickly go over the list, and some are too young or too old. I have never found it to be a completely unreasonable amount of time and a majority of the time, in my experience, the kids spent a reasonable amount of time in line, some in/out depending on age and parents didn't really stray that far.
