I booked the cruise through the Tour Disney phone number. I can not remember the cost, as it was a few years ago.
It was fantastic! Worth every penny. A great view of Illuminations, fun trip around the lake and some fun snacks. We ordered specialty cupcakes from YC private dining.
We are paying $371.00 in November for our Illuminations cruise. The posts on here, at east the original information is outdated.
Call the tours number, they are no where near as hard to get as they use to be. And you can book with the 180+10 if you are staying on site, like dining.
