FYI, I'm just an average recreational home pool player - learned on an antique (even then) Brunswick 9 footer in my grandpa's cellar at the farm (big old fuzzy wooden support post right smack against the center of the head of the table, lol, but clear shooting otherwise), we had a regular 8 foot table when I was a kid in our basement, most of my friends had regular 8 foot tables, that's what we knew. My old Anniversary is the 8 foot "pro" size. I'd love a 9 foot table, but mine has a lot of sentimental value and I like the slightly larger size vs. the regular 8 for sure and it fits the best, but when I wasn't visiting at the grandparents, the 8 footer was perfect at our house and would still enjoy it if that's what fit. Now, for me, if all I had room for was a 7, I wouldn't have a table - sounds weird but I guess no different than the 9 foot or nothing guys or gals.
OP, you say you want to have fun, not too serious, but in another post you suggest you want a 9 footer because if "looks better" - I think you are hung up on what the pros play? Nobody that visits will care if it's 8/8.5/9 and any table will look great in a room it fits in and will look awkward and play awkward in a room it doesn't fit in.
I'm no pro (but am loving reading all sorts of things on this site) but I can speak from decades of just enjoying playing at home with family and/or friends and there is no point getting a table that won't work in your room or trying to justify ways to make it fit - i.e., trying to talk me out of what I know my measurements are, or trying to convince yourself you are lining up shots with one of your feet under the table! It's easy to figure out the distances you need for using your cue, heed the advice of not leaving yourself short! And if one post is all that will possibly interfere at an angle (not parallel) and you need a slightly shorter cue for one shot, no big deal.
