Hello! I am wanting to take my mom and 12 year old nephew to Universal Studios in September. I am trying to figure out if buying the vacation package and staying at a Universal Resort with unlimited express package is worth the extra cost. Will it be super busy in mid September where we need the unlimited express passes? Also my mom doesn't want to ride any of the rides so I feel like I would be paying for something that she won't use. Any suggestions would be great!
