I agree with that. Use EMH and if you can try to be there for 8.00 at the start of EMH as it even started getting busier by 9.00 whereas at 8.00 it was really quiet - we did Peter Pan 4 times in a row as walk ons.
Also worth trying for rides during parade time as queues are shorter then.
We also tended to eat our main meal at lunch time or mid afternoon if we'd had a late breakfast which meant we avoided crowds to eat in the evening, it gave us a rest in the middle of the day away from the crowds and often the rides were quieter as people were eating.
Above all enjoy and try to take things easy. Our aim this year was to enjoy the atmosphere more and not just rush from one place to another. We did this and ended up probably going on as many rides as previous times.
