Just looked up the location of the camp, if you were to get placed there, you'd be less than an hour away from the camp I'm going to! Anyway the 12th wasn't that long ago, so I'm not totally surprised you haven't heard back yet, probably works out just over 1 working week or so. But yeah I'm sure you'll hear back from Americamp on Monday or at the very latest on Tuesday.
Me too though! I'm meeting up with the camp directors of the camp I'm going to on Friday, so I want to get everything finalised with them (dates etc) and make sure they still want me (!) and then go from there and start to get the visa, crb, medical check and finally, flights sorted. I just want to get it all out of the way, cost wise and time wise - because as you've said booking flights earlier is a money saver.
So I'm mainly concerned with wanting to book them but obviously you HAVE to have done visa, crb and medical first, so it's important to me to try and get it all going as quickly as possible.
