Sunday is no good, but Mike mentioned yesterday that he can't play next week, so Monday night (and Tuesday night) 6-10 are open if you want them. There's a travelodge in La Marque that's very close (1mile) and will be about $50 a night with 3.5 out of 5 stars from customer reviews, I doubt you'll be able to do much cheaper.
I'm not sure if you are used to Houston traffic, but evening rush hour starts around 3 and lasts til 8. If you come from the downtown museums during that time, account for about 2 hours. Otherwise it's about 35 minutes to my place.
I had a game night at my house last week and have plenty of beer left over... I typically don't drink when I play snooker though, because it doesn't help my skill level. *laughs* It's hard enough as it is.
