1 Plan Ahead!
For me and my family it's tradition to attend the Houston Livestock Show & Rodeo every year so we are use to everything. But if you are planning your first visit to the rodeo I suggest you plan your entire visit ahead of time. There will be a lot of traffic and parking can be a bit of a hassle. We always park in either the purple or yellow lot for about $10.
2 Purchase Ahead!
Tickets for all the rodeo concerts normally go on sale weeks before rodeo season begins so it would be a good idea to purchase those as soon as you can because they sell out quick. This year Bruno Mars will be the biggest act and tickets are completely sold out.
Also if you plan to visit the carnival and you have a big crowd you might want to purchase one of the rodeo discount coupon books to save a few bucks. You can normally purchase them on the Rodeo Houston website or through your kids school and they're good for most games and rides.
3 Wear Comfortable Shoes and Clothing!
In late February early March the weather is normally cool or breezy as I call it but as a native Houstonian I can ensure you that the weather is never really for certain here. I would wear a light swear, comfortable clothing, and walking shoes (because you will be doing alot of walking).
Additional Tips:
Tip: If you park in the yellow lot you can catch the free tram to the stadium.
Tip: You can get into the carnival for free if you purchase rodeo tickets. Carnival tickets separately are about $15.
Tip: Bring extra cash for food and souvenirs.
Tip: Be prepared to walk.
