We lived in LA and went at least once a week for a number of years. Then we moved out of state. We went back with our DS and it was a whole other story. I was used to just flying by the seat of my pants every time I went to
Disneyland, so it was an adjustment that first time. I had to be alot more flexible about scheduling, food, how long we could stay in the park etc. It was easier later when we went back with DD, too. By then we knew what to expect when taking kids to the parks.
This worked for us:
-Stay in a hotel you can walk to.
-Don't worry about making rope drop unless it works out naturally with your schedule.
-Check menus before you go into a restaurant.
-Try the easy rides first, like the outdoor fantasyland rides. We rode Small World 12 times that first trip. 12.
-Take an afternoon break.
-Nap if they are the age for it.
-Take plenty of snacks and drinks into the park.
-Find some quiet places to sit in the park once in a while, it's so busy and overwhelming there.
-Be willing to miss the fireworks. If it happens that the kids can stay up that late-great. If not, it's ok to skip them. Or maybe have naps and dinner at the hotel and go back later in the evening for fireworks if it doesn't interfere with bedtime.
-Use a stroller if the kids aren't too big. DS fell asleep in his a few times. He had his blanket and stuffed animal and it saved him from having to walk all day.
-Be willing to ride the rides alone, since the kids can't go on all of them. You'll need to switch off riding/ watching the kids.
-Bring medicine, bandaids etc with you into the park.
My DS was terrified of the fireworks (he was 3 1/2). We had been talking them up all day and when they started he was just screaming and crying. We had to carry him, his bag and his stroller through huge crowds in front of the castle to get out as fast as we could. Looking back, we should have ducked into a shop or something distracting and quiet. He is probably in the minority, but he really didn't like them!
I have always loved Disneyland, but it was even more fun once the kids started coming along
Have fun!
