I don't know about "saving thousands," but as far as the trip to Scotland that I mentioned went:
- DH and I paid a total of $6,400 for a 10-day "Best of Scotland" Rick Steves Tour, which included hotel/B&B, most of our food including a couple of upscale dining meals with alcohol, a guide and motor coach transportation, and all of our touring admissions (museums, castles, Loch Ness river cruise, etc.). We paid an additional $1,100 for economy airfare and $500 for additional meals and souvenirs. Total cost for 10 days was $8,000, or $800/day.
- For us to spend 10 days at WDW in a deluxe hotel (which offers fewer amenities than the places we stayed in Scotland, where we enjoyed daily hot breakfasts and even oceanside views, but it's the closest comparator) -- let's say Beach Club pool view during the same end of September-beginning of October time period we went to Scotland, with parkhopper tickets -- the total cost is $8,067. Add $600 for roundtrip airfare on JetBlue and our total is nearly $8,700. But WAIT, we're not done! Add in 10 days' worth of the DDP for over $1,300 and the total cost for 10 days at WDW is $10,000, or $1,000/day).
I realize there are ways to make the European trip more expensive or the WDW trip less expensive, but if I'm trying to craft a Disney trip that has an apples-to-apples comparison with the accommodations, amenities and activities that were involved in our 10-day Scotland tour, that's how the numbers shake out.
