I am sorry you are not having a good time. Did you ask to speak to a manager at the hotel? Unfortunately, I've stayed at POP, and with no inside corridor, I heard thump, thump, thump, all night, as people were moving their luggage or strollers over the cracks in the path outside my door. I've also had room not ready at 4pm at the Poly, and it took them to 2am to fix our not working properly door. And food left in the Poly's hallways, as well as in the Yacht Club. Sometimes, I have even seen it at RPR. If room dirty, call star services and ask to speak to the cleaning manager.
And I'm sorry, this time of year, many from all over come, as it's summer break for many, not only in the USA, there will be crowds. This is prime time when groups travel. When it's crowded, I always eat at off times. And I thought the food was in line with Disney prices. You can always walk over to SF, their food court is nice. Finally, I've seen some bad behavior in food and parks in all places, at home, and at Disney and Universal. Again, I'm sorry you're not enjoying the resort. I hope your vacation goes better today, and the rest of the time you are there.
