I'm new to Universal and would appreciate any help or input I could get. We'll be visiting the week just after 4th of July (2 adults, 2 kids ages 8 and 10). I'm staying offsite (family timeshare). I'm thinking of getting 3 day park to park tickets and then 4 day Disney park hoppers. First do you think 3 days is enough at Universal? I've also read a bit about booking a room to get unlimited express pass. With a 3 day park to park do you think that is necessary? Also if you book a room do you have to wait until check in time to get the express pass? I'm considering coming a day before or stay a day after my timeshare, but also want to consider if the extra cost would be warranted. I'm familiar with how to navigate Disney touring plans, but this is a new animal. I'm really excited to try Universal; I want to be planned and prepared to make it a great experience for all.
