Check out my favorite travel planning sites and resources

These are the sites I like for travel planning, plus items I like to bring with me on trips.

Find the best deals on hotels with Booking.com.

Book the best city tours, day trips, and skip-the-line tickets through Viator and GetYourGuide.

For travel guidebooks, pick up a Rick Steves or Lonely Planet.

For road trips, find a rental car through Discover Cars.

Book an airport transfer with Welcome Pickups.

For train and bus transport in Germany, use Deutsche Bahn and FlixBus.

For data in Germany and Europe, get a SIM card (or an eSIM) before your trip to save time.

Don’t forget to pack a collapsible water bottle, a plug adapter, and a stuff bag day pack.
