Trip to take dd 16 to celebrate GCSEs

[Babyhoover]

I'd like ti treat my dd to a trip away but have no idea where. We are in London so airports and euro star on the door step. Going Paris in the October half term have been in Copenhagen, Berlin, Brussels, Stockholm and Prague (didn't like Prague tbh). How about Rome or New York or maybe a little mini holiday in Sardinia or nice civilised place in Spain? Not sure about budget at this point

I'm taking DD to Croatia for a few days for the same reason. 4 nights, coming in at around £1800 all in.

Decided to go to Cala d'or in Majorca in the end. All inclusive for 4 nights. Going with her best friend and her mum. We don't do these kind of beach AI holidays but it seemed the best option in the circumstances as all the girls want to do is have fun by the beach and chill all day!
