It's a great budget to have, and city breaks under £500 per person can help you see places like Berlin, Cannes, Venice and many more fantastic cities. Even if you need to split your budget between two of you, there are plenty of cities to discover within your budget for 2025/2026.
To grab the cheapest city breaks, it's a good idea to be flexible with where you go and when you go. Due to higher demand, travelling at the weekend can mean higher flight prices so some of the best city break deals under budget are travelling and staying during the week. You'll also find that Sunday night stays can help reduce the cost of your hotel, as many weekenders will have left already and corporate travellers won't be arriving until Monday.
