I've been once. It was a month or so after my ex and I split. I was still living with her family (sharing a room with her jncle... ugh.) I spent the night before hanging out in Hollywood, got in at like 6am, and crashed on the couch. I was work up at like 8am by her Mother asking if I wanted to come with. They had my ex's stepsiblings staying with them, who absolutely loved me, and wanted me to come. So I got my ass up, showered, and went to Universal Studios. 2/3 of the kids were being fussy (2 and 4 yrs old), along with my ex being a bitch the entire time... they only ride I went on because of that was Jurassic Park. My ex's sister (15) and the oldest step sibling (9) and I stood in line for like and hour and rose it. And then the Backlot tour. And then everyone wanted to go home. It was kind of a let down... but it was free. Can't complain too much.
This time it will be different.
