You can not make the argument for buffet prices!!!! I won't allow it on my thread! Chef Mickey's breakfast would run you specifically $140+ tax + tip....So, let's say $170? I get doing it, because I have done it, but good golly, I wouldn't call it a value....
Your park tickets work out to about 100 per person per day. I still think that's a good value, if it's for a hopper. If it's for a single park, not named Magic Kingdom, I am not sure it's worth it.
I can make the argument for the buffet as a food and entertainment option. Meal and a show. I made the argument earlier based on the cost of my lunch today. I stupidly forgot for a few minutes that I'm not going to the nearest fast casual place for lunch today. I'm going to a
AMC Dine-In theater to see Captain America: Civil War (WOOHOO). My movie ticket cost me $14.37. I will also have likely what I had last time I went there, which is the Big Bite Sampler (appetizer platter) for $12 and a single beer at $8-10. Rounding, addingTax+tip, I expect to likely pay $25+ for my food, and $15 for my movie. All told, $40 for lunch. If I took my family, it would be similar, though the kids might end up paying a touch less for "kids meal" stuff.
It's a similar cost to the Disney buffet, just different entertainment options. The Disney buffet may be a touch more expensive, but not outrageously so (yet).
I could also argue the cost-value of time/money. If I were to want to take my kids to see Mickey, Minnie, Goofy, Donald, Pluto, lets pretend on average I spend 20 minutes in line for each (we can quibble over methods of this, Epcot Photospot, etc of course). 100 minutes of my day waiting in line to see the 5 characters, plus the time I'd typically spend eating a meal, let's say an hour to compare sit-down to sit-down. 160 minutes out of my day to see the 5 characters and eat a sit down meal. Now, if I say I'm going to get 10 hours in the park on an average day, that's 600 minutes. 1/4 of which would be spent to see the characters and eat the meal. That equates out to $18.75/person based on your $75/day theme park ticket. Combining your meal and your character experience together means that instead of 25% of your day being spent doing those two things, you now only spend 10% of your day doing them, or $7.50. Taken on face value, saving you the $11.25/person doesn't seem like it takes too much out of the $45 dollar cost of the meal, but remember, you also gain in efficiency by being able to spend that 100 extra minutes doing other things that may be of value to you, giving you up to 16% more experience for your $75.
Now, I'm not saying I %100 agree with any of what I just wrote. Just know that telling me I CANT argue something is just asking for trouble
