You are not comparing apples to apples. I don't know what the Clarion is like, but, it would have to be way, way better then All Stars Music. You are trying to compare a 4 star to a 2.5 star or you are comparing rack rate to a special offer. Who pays the rack rate anyway? $550 for car rental? Are you renting a Rolls Royce. $180 tops for a week in central Florida. $100.00 for gas? I drive from Raleigh, NC to WDW and back for $94.00 with a Cadillac Deville V-8. $20.00 per day parking fees. Big deal. I never have paid more then $60 per night in any offsite hotel. 5 star... NO! I'm only there to sleep not spend untold hours in the place. And I am usually within two miles of the welcome sign in WDW. I haven't been to All Stars, but, I have stayed in POP and the bathroom in a Quality Inn is bigger then the entire room at POP. OK, slight exaggeration, but, there seems to be some discrepancy in your numbers there. You didn't say how many days you are talking about, but, using the parking fees, which also are incorrect now, it's 7 days. If it is 7 nights for accommodations, then the most I would be paying is $420 to $500. Quite a distance from $1743. Anyway, I have already said the if one wants to stay onsite, then that is fine, but, those numbers you are using are not even close to actual costs. Add in meals that would average $45. per day offsite, $315. per person, and that isn't McDonalds. They may be chain establishments, not all, but, the food is just as good as on Disney and the bill is to die for.
So let's let other people know that if they are struggling with having the money to go to Disney and they would like to, there is an alternative to staying onsite. Many, like myself, do not have a problem with driving in the area, it is made to sound worse then it really is... I wonder who's spreading that rumor. I don't need 24/7 immersion to enjoy it, and I suspect that I am not the only one that feels that way. I can take a 10 minute drive to any type of restaurant I want and do it exactly when I want to without having to have a reservation or worry about getting there on time or I can use Counter Service. To me that beats old magical rodent to pieces. That is especially true if you either go offsite or you cannot afford to go at all.
Someone said "rat invested" when referring to offsite accommodations, which thanks a lot for the insult, but, even if it were true (it isn't) should we mention the number of rats that are wandering around the food areas all over WDW and every resort has a food location whereas not every hotel offsite is also housing a restaurant. So who has the rats, you might ask. I'm OK with you not wanting to pursue this because you have done research and know better, however, I have the credit card statements that say otherwise... that my friend is fact and what you are putting out there as fact, is nothing more then who you asked.
