I disagree.The analogy that I believe describes the current situation: you buy a ticket to a baseball game for $100. Included in this ticket is a hot dog, nachos and a drink. You have been buying this same seat for multiple seasons. On the next homestand, you get the same seat-except now, team/stadium management has removed the food from the price of your seat, so now you pay $100 for the same seat, and have to pay the extra $20 for the food. You still have the option to pay more for better seats, but you are now paying more to get the same thing you got before with the purchase of the seat you currently have.
Genie+ is not the same product as FastPass+, it's better. It's better because fewer people are using it.
To keep your analogy going, you have to pay $20 extra for the food, but it's not the same hot dog you used to get. It's a sausage and peppers with a beer.
