Hey,
dh and I worked for PGL for several years as group leaders/instructors/in teh kitchen. This was about 10 years ago now though.
My first summer there I looked after the 6 to 9 year olds in a group while they were there. Its a pretty strict routine of up, eat, activities, lunch, more activities, dinner, evening entertainment, bed, however going to bed did not always mean sleep!
For their age groups they used to get time out half way through the week to catch up on sleep if they needed it, but mostly they were just hyper all the time, just the way they should be .
There are "procedures" in place to deal with homesickness and any other problems, but all of the people I worked with (well 99%) had a good deal of common sense and showed sympathy for the kids when needed. They are so busy they dont have time to worry about things.
Since we worked there I believe the staff have had further (and better) training, posh uniforms too.
I would send my son, maybe for a short week first then build up to a week if he wanted to go back. Or you could stay near a centre and take him in for day camo everyday and pick him up at 6?
I would, because ive seen how much fun it is
Sorry thats longer than I thought!
