Just got tickets to see the Orioles next month!

Been trying to take my boys (9 and 11) to a real MLB game for like 3 years and finally scored some decent seats for not-insane prices. They're pumped. Camden Yards is supposed to be beautiful. Anyone have any tips for first-timers? What should I know about parking, getting there early, etc? Also lowkey nervous about the cost of stadium hot dogs lol
