I tell people I'm going to Florida... I honestly stopped saying too much to people after the "again? Really?" Type responses.... I don't like wasting my time when people are disrespectful about it - and I prefer to be nicer than mean 
What matters is we have a good time, my money, my vacation...
I honestly don't let my family I on it too much (mostly brother & sister) because apparently if I have extra money I should funnel it to them
However my parents bought DVC 20 years ago (which was transferred to me) so the trips are understandable to them. We just introduced part of DHs family to Disney in December. They never said anything but I don't think they understood either (they are super nice) now they want to go with us every year
They told us what we did, the fun we had, and the little tips I gave them when we took our kids back for naps really helped them have fun...
And honestly I think deep down they are all a bit jealous
