True. It was our first time to stay on property and our first time there since we were kids so we didn't do any planning. Didn't try to cram in every ride and show. Our typical day was to go to an Early EMH, explore that park until lunch, then go back to the resort for a nap, etc. We'd go back to the parks at night for dinner and some more rides (Usually Epcot).
Just relax. Think you are on your honeymoon, not that you're at disneyworld. Stroll from attraction to attraction. Wait for the crowds to leave. Our best memory was leaving dinner in France at 9:45 and walking the long way around World Showcase with the park basically to ourselves. All the torches burning and millenium celebration music playing in the background. "We go own" can be an increadibly romantic song.
