suzanne,
Thank God! Leroy adjusted well, went straight into US time but for the 1st couple of days he woke up in the middle of the night for milk after that he will go back to sleep. I think on the 4th day, he slept through the night already. When we got back to Sin, it was the same thing. So i didnt have any problem with jet lag. Leroy really enjoyed Disneyland, he took most of the rides except those which he failed to meet the height requirements. Those which he was allowed on we went on all of them, i marked out every single ride. Hehe..we got there at 10am n left at 7.30pm. The queue wasnt that bad, u can take the fast pass for the more popular rides so it saves u some time. But it really depends on yr boy cos some of the rides r quite rough n its quite dark inside. L v garang so he squeals in delight n was v excited. BUt some kids cried. so use yr own discretion.
