When your Bed & Breakfast is ready to welcome guests, a bell image  will appear on the lower left corner. You can also invite your Facebook friends to visit!
To invite friends, tap on the Guestbook  on the lower left corner. Under the "Friends" tab you'll find a green "Invite" button. Tap on it to choose a channel where you wish to share the game.

If some of your Facebook friends are already connected to the game, you can immediately invite them to visit your Bed & Breakfast by tapping on the blue "Invite" button in the Guestbook 

Your Bed & Breakfast guests will obviously pay you for each stay once you check them out.
