I mean a little common sense will take you a very long way.
it's freaking universal studios. it's not starbucks or the bar you have been to 200 times. I have been to universal studios 3 times since i have lived out here and every time there has been no less than 6 of us, it's a group type thing that's what you do. no one goes to a freaking theme/amusement park by themselves or with 1 person.
Also I will add, one of the things that women find attractive ifs a guy who doesn't press. I know you want to get laid, but if that is litearlly the only thing on your mind you won;'t get anywehre with anyone. you have to know how to kick ti and ahve fun and take what life throws at you. there is nothing attractive about a guy who is so one tracked he doesnt' want to enjoy a group outing at universial studios beucase he is afraid it's going to take him longer to get in her pants lol. to get in her pants you have to push her excitement/fun buttons and your actions aren't pushing those buttons right now. sex is simply the climax of a freaking great time. if you have fun with her and she really enjoys you the sex will come i assure you, but the attitude that you aer taking is counterproductive.
go and have a good time, get on some rides, take some pictures, get some food, have a good time.
you are reading way too much into this.
