In a single day, you can only help up to 5 times on the islands of Union members and up to 3 times on the islands of your friends or subscribers, so make sure to plan wisely.

You can help players by speeding up certain actions on their Islands such as events in hotels, construction, upgrades, or building repairs. Visit other resorts from the Friends tab. Pay attention: if a player needs help with a particular building, a corresponding icon will appear above the required building.
