<human>:  I am planning to travel to European cities this summer, what steps can I take to prepare for this?
<bot>: 
1. Spend some time researching the cities you'll be visiting and what kind of activities they offer.
2. Check the current entry requirements for the countries you'll be visiting, as well as any travel restrictions in place.
3. Make sure you have a valid passport and all necessary visas.
4. Consider whethe you will need to get any vaccinations prior to your trip.
5. Set a realistic budget for your trip so you don't end up overspending.
6. Look into flights and other transportation options, booking well in advance to get the best deals.
7. Arrange accommodation in advance, so that you know you have a place to stay when you arrive.
8. Make sure you have suitable insurance that covers your travel and any activities you intend to do while abroad.
