What are some fun, daytime (bachelorette) activities in Austin, TX?

We’re planning my friend’s bachelorette party in Austin, and I have never been. I’m not a big partier, and I’m not super outdoorsy, so what sounds fun to me would NOT be what she wants to do. Just an aside, but I’m a SAHM who is spending waaaaaay too much money on this party and their wedding already. The other girls suggested tubing, but I cant imagine spending almost $100 to sit in a tube on a river, sober, with a group of girls I barely know, for 3 hours!! 🤦🏼‍♀️ I’m in way over my head. 😂 Any suggestions, expensive or not, would be extremely appreciated!! Thanks in advance!!
