Even though Disney does have a lot of pay-upgrades, it "felt" a lot less greedy than my first day at IA last month. DH had to stop by guest services to pick up our tix after buying online. The line was so slow and when it was finally his turn we found out why. For 10min the guest services person tried to hard sell him different up charges. We walk into the park and every gift shop had big "buy express pass here" signs. Several times in line a cm (?) told me "you can get out of this line and go buy an express pass, would like me to help you?" The worst was at lunch in HP. Getting in line, directed to register, and at register: "do you want to buy the meal plan?" three different times. Add in all the pay-to-play carnival type games and by the end I was exhausted from saying "no thank you, I do not want to buy that."
I liked IA, loved the HP section, can't WAIT to visit Diagon Ally, but was was still so happy to get back to less-greedy disney.
