I really like shooting night shots without flash but carrying cumbersome tripods can be really inconvenient, especially if you are on vacation. Last January I went on a weekend getaway to Disney with my mom, so I thought I would give the Gorillapod a try. You obviously don't have as much flexibility as with a standard tripod but it gets the job done and you can get some great shots.
This was taken at Port Orleans Resort where we were staying. There is a little foot bridge that takes you to the main lobby and restaurants from the rooms. I wrapped the gorillapod around a support beam from the bridge and ended up with this shot (8 second exposure). Hitting the shutter produced considerable camera shake since it wasn't on a flat surface so I had to use the camera timer.
If you decide to get a gorillapod make sure you get the right size because the smaller ones won't support a heavy SLR camera. A couple of things to note is while its really light and portable its not very sturdy and it may be difficult to achieve the composition you want if you don't have an existing raised surface (like a table or bench) or something to wrap it around.
