In portal island there are many, many portals, but there's no way of knowing what portal leads to where. Some portals are self explanatory (ex. crystal forest) while others are just scattered around. so my idea is that there could be signs that tell players the name of the world a portal leads to. Or a player can hover their mouse over a portal and the name will show.In my opinion it would be easier then going to a portal, finding out its the wrong one and coming back to portal island to try who knows how many other portals.
