A bit on the pricey side for 10 minutes of entertainment but you are in Vegas after all. I would only recommend this for couples or when you are trying to woo a lady. We received a private gondola even though we only paid for the shared gondola which was a huge bonus.
Our capitan (or whatever you call a gondola paddler) had some fantastic vocals and really helped transform our ride into a Venice experience. The indoor and outdoor gondola rides are two different experiences also by the way and since it was about 40 degrees outside we opted for the indoor gondola. The entrance to the indoor one is right across from Barney's inside the Venetian Canal Shoppes. You can buy tickets just around the corner inside a gondola gift shop. Excellent date night material and overpriced family/friends ride so you make the call from my .02 cents.
