Just a couple of questions....

How/when can i find out about the exact dates

Do you need to book accommodation far in advance

How busy does it get? I am backpacking with some friends and we were wondering whether this would be the best time to be on CC. we would like to meet lots of people our age (20-22) but don't know if there are many more backpackers at this particular time as i presume everything is a bit more expensive then. are we as likely to meet lots of people either a bit before bit after when it is less expensive (if that makes sense!). Like the sound of lobsterfest but worried re costs and accommodations.

thanks!
