Oh I HATED the paper slip. They were still using that in 06 when we went for the first time. We were not told we needed it to get into MM unti, our first time. They let us in, but made sure we knew to have it next time. I LOVE the new key to the kingdom. It was so easy at WDW. I love DL has it now. My 4 y/o dd only needed her hopper, but they were asking all others for the key card.
