If you have bought a ticket for the concert that night you will have automatic access to the fairgrounds and the buildings but you will have to pay for tickets to ride the rides

You have lots of questions! 1. They will announce all of the Rodeo performers tomorrow and the 3 Friday performers on Feb 4. I don't know why. 2. Most of the tickets (all of the decent ones) are in season tickets. They will put the single performers on sale at some point later this week, but most of those seats are upper deck. The lower deck tix are $30 and they upper deck less. The club level a bit more. There are great screens, but..... 3. StubHub has lots of offerings, but..... 4. You can also just pay to go to the carnival and livestock show. 5. Transportation: since I don't know where you'll be coming from, I can only tell you what goes by NRG. There is a light rail from downtown and points in between. It stops at NRG. There are points around the city where you can park your car and catch a bus straight to NRG. Uber goes there, but trying to get one after the show is a LONG wait. 6. It's all lots of fun----enjoy!

Rodeo usually starts end of February and runs through 2nd or 3rd week in March

Included in concert. But if you want to do the games/Carnival part then it will be a separate fee.

Existen dos tipos de tickets y depende de lo que quieras disfrutar.... Uno es para entrar a la feria y poder disfrutar de la exhibición de animales y la feria de atracciones La otra entrada es para lo dicho anteriormente e incluye la exhibición del rodeo y el concierto, es más costosa pero para la primera vez, vale la pena .... sólo asegúrate de escoger bien al cantante que se presenta ya que todas las noches es uno diferente Disfrutalo

They are not all year round at the NRG stadium. There is one in Galveston in September which is a couple hours from Houston. Billy Bob's in Dallas/Ft. Worth has a lot of small rodeos but that's pretty far from Houston. If you use your search engine using Houston Calendar of Events, you can see what's happening in September 2019.

The most popular thrill rides can require a number of ticket so they can go through them quickly.

Yes, you may arrive later. The rodeo begins at 6:45 p.m.; the concert typically starts around 8 or 8:30 p.m., and lasts about 1 hour to 1 1/2 hours. Another tip: If you're close to one of the park and ride locations, use those for trips to and from the rodeo/concert. NRG parking can be as high as $12/$15 vs $4 (for the Metro Bus) or $7 in the Rodeo Park and Ride lots.

Not sure what Rodeo’s will be April 19 but the Houston Livestock show and Rodeo which is one of the largest is February 24- March 17 2019. Sorry but hope this helps some.
