So what you said here is that WDW going to each park then sitting at a pool is comparable to the beach? I disagree. Just like sitting at a pool at the beach is a waste, sitting at a pool at WDW is a waste, I can do that at home. The beach is the vacation and the parks are the vacation. That is what you compare, to which I do understand that most here glorify Disney. I do not, I put it right at the same as any other vacation destination.
I did compare the exact same week in June when the kids get out of school, Disney for 5 nights and Myrtle Beach for 5 nights and the cost, assuming from experience plus the cost of eating out for dinner at the beach. Disney was twice the cost not including travel (by car, Disney is <2x the distance.)
That is comparing a complete beach vacation, ocean front lunch in the room and dinner every night vs. full Disney vacation at Disney resort with Disney transportation, dining plan because of lack of ability to easily eat lunch in the room.
Do some rooms at WDW not include refrigerators? I think you can easily cut your 300.00 food budget in half by eating sandwiches in the room or even take them w/you to the park.
