It's almost always possible to add an extra night in the start or end location of your tour.
Check the "Price" section on the Dates & Prices tab of the tour page to see if extra nights are an option. If so, simply include the extra night(s) in your booking request.
To add an extra night that's not on the tour route, we encourage you to book through Hotels.com. Or if the idea of staying as a guest in a private home appeals to you, try Homestay.com.
