I know it's not my business, so forgive me, but is a trip like that more expensive than a cruise? I'd love to do a trip like that one day.
No need to apologize, I don't mind talking about it. I love "promoting" DVC and would recommend it to anyone, so your question lets me do that
Yes, it's DEFINITELY more expensive. Using our exact dates, resort, room type, and tickets as an example - this is what you're looking at:
CASH/NOT DVC: Animal Kingdom Lodge/Villas in a Savannah view studio room for 10 nights plus 10 day base tickets (our dates, which is the cheapest time of year to go) for 2 adults (baby is free) is currently pricing at $5,776.14. That does not include airfare, food, or any "extras", that's ONLY the room and tickets for 2 adults!!!!
With that said, we are DVC members and pay $0 for the room and the 10 day base ticket is $636 total for 2 adults. In addition to that we have about $900 in airfare plus all food. We are doing a LOT of character and special dining which runs $40 - $60 per person. (I think Ryan budgeted $1,300 for food for an 11 day trip; most families with kids would probably eat cheaper than that though).
Now - with that said, since we are DVC members and essentially get our room "free" - we are in a deluxe property. That same length of stay in a value resort is WAY cheaper, 2 adults with room and 10 day ticket is only $1,986.02 (again, remember that you're going to still need airfare, food, and extras). Obviously, if you have kids then it gets more expensive. They have specials sometimes where they offer their dining plan for free, etc, but that's a personal preference. Ryan and I have always just gotten the tables in wonderland discount card and bought our food as we go. Since we do a lot of higher end dining and character experiences, it's cheaper than paying cash and getting the discount than wasting dining plan points. (I can explain if this doesn't make sense). All in all Ryan will spend bout $3,000 on the trip because we're DVC members. Without being a DVC it would be costing about $8,000. BUT, like I said, we get deluxe rooms because of DVC. Without it we would probably be in a value resort, in which case the trip would be about $4,000 when all said and done.
Really, it's a hard question because it depends on your preferences of where you want to stay, how you want to eat, extras you want to do, and time of year you want to travel. Above is just based on us and our preferences/situation.
I hope that helps! For the record, with DVC we didn't pay a penny for the cruise - not even port and tax!! We only pay gratuities and any excursions or extras we want!

I HIGHLY recommend DVC to anyone!!
