Hello
I fell in love with Prague.
Prague is a wonderful city.
The Prague castle was especially nice.
Tomorrow is scheduled for skydiving.
Do you have any more suggestions?

The Cross club is a legendary place for instance: http://www.crossclub.cz/en/contact/
And if you liked the Prague castle, you would enjoy Vyšehrad either: https://en.wikipedia.org/wiki/Vy%C5%A1ehrad
