We're thinking about making our first trip to Universal Studios/IOA next week, possibly Monday, Tuesday or Wednesday. Any idea what the crowds will be like and which of these days will be least crowded? I don't think we're going to buy an express pass so I'm hoping it's not too packed. Also, we have 2 kids (9 and 11). Do we need two days to cover both parks? They like rides so they'll go on everything they can. Thanks!!
