Travellers would like to visit up to three buildings in your town. There are currently 8 buildings that you can place on your map: Inn, Carnival, Gift Shop, Restaurant, Dancing School, Theatre, Fair, School of Magic. Level-up your Fairytale town to unlock new buildings. You will need coins to do so.
At the beginning each building can fit only one traveller, but you can make upgrades to serve more travellers at a time. Serving time is different for each building, 1-4 hours. Each building can be upgraded. Just use different tools that you receive from the travellers.
