It depends...
With family, we typically are the ones who invite them to come along, and we do not ask for or want compensation for the points. However, this policy may eventually be changed! DD has now canceled on us at the last minute twice. Both were very good excuses... the first time she was running a very high fever and the second time is literally right now (we should be driving to Disney as I type this!!!). Atlanta (where she lives) is covered in ice and her office has been closed for three days now. As she's an accountant and it's year-end, she now can't leave for her extended weekend vacation with us... and even if she could get off work when it finally reopens tomorrow (which her boss already said would be impossible), she'd be hard-pressed to get a flight out. So yep, a good reason. But also, a good reason that is not covered by
trip insurance. Amazingly, they do not have coverage for ornery bosses or ice storms that happen earlier in the week!!! =P Since the trip was planned for dear son-in-law's birthday and they are no longer going, none of us are going and I canceled the reservations yesterday. Now we have greatly devalued points sitting in holding and very limited travel options before their UY expires. Situations like this are very frustrating... and honestly it does make me rethink the wisdom of not asking for any compensation from those who travel with us.
All that said, though, we greatly enjoy traveling with extended family, and offering the rooms for free allows that to happen more often. We are still hosting the entire extended family in May to celebrate our son's graduation... with us covering the villas for everyone. We will be covering the cost of only one meal... which is a doozie of a meal (Queen Victoria's room for all of us at Victoria and Albert's!!!). Extended family will be responsible for the rest of their meals, park tickets, and their travel to Disney. We do have a few additional communal reservations for dining, but typically we rotate those dinner bills among the parties (we pick up one meal for everyone, brother's family picks up one meal for everyone, etc.).
For OUR friends, we've traveled with fellow
DVC'ers and they've made their own reservations or we helped our non-DVC friends rent points to stay in their own villas (rented from someone other than us, with our friends paying the rental amount). That way, we were not asking for money from our friends, but we still could enjoy traveling together. That also insulated us from the hard feelings that could come if friends could not travel at the last minute.
For our KIDS' friends, when we invited a guest, we covered everything... travel to get there, room, food, tickets, everything. In this case, our family would be going and having a great time even if the friend could not come. So, the risk of points going totally unused was really very small.
