Lisa, I strongly recommend that you take them, but also you need to look up on youtube how to use 'em!! Practice using them after you've watched the videos. Try going up steep hills with and without them, you'll notice a difference.
Also buy yourself a couple of rubber stoppers for the ends of them so that you can move along silently without getting on other pilgrims nerves.
Be aware most airlines won't let you carry them as cabin luggage.
