I was fortunate enough to experience both last December! I enjoyed both. But Illuminations cannot be matched! It was absolutely amazing. I felt like I was actually part of the show. However, if you can't get the Illuminations cruise, you need to see it from inside the Park. Don't miss it. Also, if you can't get the Illuminations Cruise, go ahead and do the Wishes Cruise. You will enjoy it. It's a nice, relaxing way to see the fireworks. It's a totally different perspective from inside the Park. I recommend seeing the show from inside the Park as well -- in front of the Castle just to the right. It's AMAZING! As far as the music, only the Grand Gatherings boats have the music. If the wind is blowing the right direction or your boat sits by one of the Grand Gathering boats, you will faintly hear the music. Enjoy!
