We were with a group of 7 other friends and loved the cruise because it was SO relaxing. My GF felt like royalty, reclining on the seat of the boat and not having to stand/walk. Our driver was incredibly funny and I felt like we got two shows.
That said, the view had pros and cons. The boats line up side by side under the bridge. I was somehwat concerned that we might have smoke in our eyes if the wind was in the wrong direction --- which can happen --- but everything worked out OK. The view of the fireworks was fantastic, but we felt too far away to see the scenes projected on the globe on the lake. That part disappointed me because we missed some of the beauty and message of Illuminations.
Glad we did it, and not sure I'd spend the $$$ on it again.
