Alaska - How can a group of 8 see bears?

[bzss7x]

Hello,

I will be a part of a group of 8 that is cruising Alaska in late July. One of our stops is Ketchikan. We all would love to see bears and understand that it can be costly. However, while doing research for the trip, we realized that most companies fly DeHavilland Beaver aircraft, which usually holds up to 6 passengers. Are there any companies that can accommodate our larger group?
Any advice or experiences will be appreciated.

TIA.
