Our revels now are ended. These our actors, As I foretold you, were all spirits and Are melted into air, into thin air: And, like the baseless fabric of this vision, The cloud-capp'd towers, the gorgeous palaces, The solemn temples, the great globe itself, Yea, all which it inherit, shall dissolve And, like this insubstantial pageant faded, Leave not a rack behind. We are such stuff As dreams are made on, and our little life Is rounded with a sleep. mycroft16 on Twitter
They board on the side of the island. You can see them change the raft from the Mark Twain Dock.
You can also watch them switch (Put the candles on the raft etc.) from in front of Splash Mountain. I recommend watching sometime, it's quite interesting. Also if the characters see you (especially the monkeys) they will put on a little show for you.
