LOL - so true (as a NY'er myself and living right on the Hudson, I wouldn't even swim in it)!
So glad this thread came up as I was going to post the question as well (and I am by no means a coffee snob but require my 16 oz cup of joe to get me through the day)! When we were there last month and stayed at POFQ, the coffee was absolutely disgusting and I couldn't pinpoint the reason. I tried both the packet in the room using Zephyrilis bottled water, as well as purchasing a cup at Sassagoula Floatworks, and both were just off. I was previously at AKL in Nov 2017 and the coffee at the Mara was perfectly fine, so wasn't sure if the composition or brand changed in 9 months time (or does AKL have different coffee than the moderate resorts)? Either way - I couldn't wait to get back home to grind my beans (good old Columbian Roast from BJ's)!
Does anyone remember the "Mickey's Diner"/"Really Swell Coffee" which was sold in the canisters in the parks? What brand was that?
