Mike,
You're spot on about Pickleball becoming so popular. So much so that in some cases resorts are failing to keep up the pace in building facilities for Pickleball or, in some cases, trying to use tennis courts (or even shuffle court courts) as multiuse facilities.
The later of the options tends to create a good bit of conflict between two complete different athletic groups not to mention younger players vs older players (Pickleball vs. Tennis respectively).
If a resort wants to keep both groups happy then they better step up to the plate and offer all venues for dedicated use or risk loosing one or the other types of RVers (or at least be prepared to deal with the issues of conflicting user groups).
