Illuminations cruise can be fun but will be expensive. I did a review on allearsnet, here's a copy:
Pros: view cannot be beat as long as the wind is your friend; good skipper makes this a fun night
Cons: ridiculously expensive unless you can fill the boat
The price of the cruise is pretty expensive if just a single family goes on the boat. If you can split the costs with another family/group, its certainly a lot less sticker shock. Also, the skipper of the boat plays into the overall experience. If he/she is good, your sense of value and experience certainly can go up. Our skipper was a RCID firefighter and since we were all firefighters or EMTs on the boat, it made for easy conversation and the "VIP" experience.
You board at the Boardwalk marina and will get a good cruise over to DHS and back. Our skipper pointed out all about the hotels and other features along the way, which was quite interesting. Then we turned around and went back towards Epcot and parked under the bridge between UK and France. This is as far as you will go. You will also be tethered side by side with at least a half dozen other boats since this is the viewing point for all cruises. Its pretty congested here and if you are looking for a romantic cruise, it will be as long as you don't mind 50 other people on boats up against yours Wink
Great view of the fireworks and I can understand what other reviewers stated about the wind. If the wind is blowing ANYWHERE but towards you, its awesome. Once it shifts, prepare to feel like you are sailing through a 17th century pirate ship battle. Lot of booms and all kinds of acrid black powder smoke hanging low and making it impossible to see anything. This almost happened to us but luckily the wind changed just before the "wall" got to us.
Overall, it was a great experience. My only downer is the price. Maybe because I've seen Illuminations 20 times from land before I finally did the cruise? Regardless, seeing fireworks at the cost of $300 for a 45 minute boat ride is still a bit pricey.
One other VERY IMPORTANT thing to keep in mind. Once you are done, the boat takes the scenic route back to dock. If you are staying at any hotel other than Boardwalk or Beach, you have 2 choices: walk all the way back through Epcot to the buses or simply go to Boardwalk/Beach and get a cab back to your hotel. Even after about 60 minutes since the end of Illuminations, we walked all the way back to the bus for CB through Epcot and still had to wait 45 minutes for a bus because of the crowds. A cab from the Boardwalk would have been a better choice then the long walk and the long wait post-cruise.
