Decisions on family vacations

Yes, for sure.  I think that having a vacation with some of this and some of that is always fun.  For example, you can go on a vacation to California and see beautiful nature, cool cities, shop, do adventure activities, etc.  You can for sure do some of what everyone is looking for.  You can also sit down and throw out lots of ideas and come to an agreement.  

yes, I think so. The key here is compromise. Once you shortlist the destinations, then it's time to sit down with the entire family and discuss the pros and cons. As this is a family vacation, everyone's opinion should be heard and considered.

Yes. I do think that a family do agree to something every once and a while.

Yes, although its probably not easy, especially if there is a wide gap in age. What you should do is get a list of some of the best family vacations and have people vote whether or not like would like to go there for a vacation. Then, when everyone has voted in the various places, see if there are any where everyone said "yes" to the given vacations.
