My first time – advice

Hey guys! I’m (31F) going for the very first time to the NRG stadium to attend the game against Bears. It is also my first time attending a NFL game and also my first time in Houston. I’m going from Guadalajara, Mexico. Do you all have some advice on what to do, what to eat, what should I know o whatever you wanna share? I’m planning to arrive at 11 am to the stadium to watch the other games, what do you think? I was told that if I get in the stadium early, I can go down and see the players warm up. Is that still a thing? I’m going with my gf and we will arrive on Thursday -will go to Astros game too- and leave on Monday. Thank you in advance and Go Texans!! I’m super excited.
