We're thinking of booking a private fireworks cruise (for Magic Kingdom) for June. There will be 8 of us (4 adults and 4 kids - ranging from 6 to 14 year old). It sounds like there are 2 types of boats - one that seats 8 and one that seats 10. Is there any difference between the 2 besides the size & price? I called but the person who I spoke with wasn't familiar with it. Thanks!!
