Tennis courts in Stuttgart for one-time play

There are not so many Stuttgart members here that you are likely to get an answer. The most sensible is to look at Google and figure out which tennis places have indoor facilities and locate them on a map to see which are the most conveniently located for you. Then simply call, or get someone to call and find out.

Your profile mentions Stuttgart-Ost but I don't know exactly where you live but I did a search at Google for "Tennisclub Stuttgart" which results in a map of the Stuttgart area with all of the tennis clubs and includes their address and website. I have listed the first 3 in proximately to Stuttgart-Ost but you can do the search yourself for more complete information.

I took a quick glance at the websites listed but did not see information about non-members playing. Facilities pretty much all belong to clubs and they might have differing rules. But it only makes sense that people would get to check out the facilities before joining. If a place only lets members play then just ask them for a chance to visit with the intention of joining up if you like it.

I don't know any of these clubs myself, so my listing is just to inform and not endorse any particular place.
