Seem like some really good prices, especially compared to other operators (Expedia cheapest two day break to Prague is £152 pp).
Prague is a beautiful city, well it was when I was there 10 years ago! Standing on Charles Bridge when it's all lit up at night is one of the most magical places to be.
I'm sure inflation and the exchange rate have had their effect, but you used to be able to get a pint for 18p!
Deals all include flights, hotel & breakfast, including:
Prague £74 pp
Barcelona £91 pp
Amsterdam £114 pp
