Hi we have an 8 year old who is soooooo shy at home but on holiday changes and talks for england,last year she made freinds with some turkish children on our complex and spent most of our holiday with them having great fun teaching them a few english words and learnt a few turkish ones too,i realise ahe is a little younger than your lad siemli but maybe he might enjoy a visit to the water park plenty of teens there lol.Hope you all have a lovely time,be positive not negative x
