Question for people who travel to/from Gib regularly

I'm planning a cheapish trip for the eclipse next year in August 2027 and hotels are just insane prices so not doable. If I fly into Gib airport, what sort of questions would I get asked? Specifically do they ask for proof of where you're planning to stay? Hoping I can fly in on the 1st Aug, sleep outside somewhere, then fly home after the eclipse on the 2nd Aug.
