I agree with the above poster, it all boils down to the relationship you have with somebody BEFORE you bought your DVC. My parents, love em to death, have travelled with them for years and now that they are older and not able to afford to travel, it was a given for me and my husband to not charge them one cent. For my sister who I also love dearly but have never travelled with, who doesn't hesitate to tell me how annoying my kids are (still have no idea why she would even want to travel with us except of course to get a freebie) and who has never done anything for me or our mother when we might have needed it, well that's a different story. I love her but I don't feel I owe her the same privilidges my parents have earned. I also think it depends on who does the inviting. For people who invite others to join them, then yes, you are obligated to pay unless you specify they are invited to join you for a certain amount. However, when you have somebody in your life who has no qualms about inviting themselves, again, whole different story. Frankly, as soon as my sister and my friend assumed they could come along for free, I assumed they were the last people on earth who deserved such special treatment. I also agree that not everyone has enough points to share. You can't share what you don't have. If my husband and I were a couple with no kids, we might invite another couple along with us to share a one bedroom. But our two kids make it impossible to share anything under a two bedroom. And lastly, for my family, we go to WDW for quality time together. Between school and work we have very little time to hang out just the four of us. So its also a matter of me not wanting to share important family time, not just my points. We all have different situations, so to say " I can't imagine not letting others use my points" is merely a personal decision based upon a personal situation. Not something that can be expected to work for everyone.
