Use Control Variables to set a value for your random number. Choose the Random option, enter 1 as the low number, and for the high number, enter however many possibilities you want for the destination (my example uses 5).
Then create a series of nested conditions, and inside each one, put a different destination.
All you're doing is setting a variable to a random number, and then taking an action depending on the value it contains.
If you have a LOT of locations to teleport to, there's a more efficient way of nesting the conditions, but I won't go into it here. Someone who's more awake than I (it's 1 in the morning) might like to expand on that.
