Is the garden in Alice's Adventures in Wonderland a Macguffin? Getting there is what drives the plot for the first, what, 75% of the book. Of course, when she gets there, something actually happens that contributes to the plot (the game of croquet and all the misadventures with the Queen of Hearts) - so is it a Macguffin or not? Same goes for the possibility of becoming "a" queen in Through the looking glass.
