Family trip

I am travelling on a family cruise to Roatan in March of 2019. The group consists of a big age range. The ages range between 6 years old all the way to 77years old. We are looking for suggestions on things to do that everyone may be able to do together as well as any reputable private tours we can use while in port. Trying to stay away from the normal cruise excursion that is high priced. Thanks for all of your help.
