Great summer camp for teenagers.
Young teachers, a lot of amusement after school, a lot of excursions. There was even a long list of additional trips (optional and for additional payment), but there was little free time, almost every minute was busy. Everyone got a certificate of participation. Every day we had a lot of fruit, had dinners in the local dining room of the national cuisines - Thai food, traditional British dishes.
Not cheap, of course, even by the standards of England, but we were ready for the price - but the absence of commissions was pleasantly pleased, because when you pay a rather large amount for the camp itself and for a return ticket, any opportunity to save is a plus.
