I have no fundamental problem with guests just meeting up or visiting. What I do have a problem with is the guests visiting the pool or spending the night exceeding the occupancy limits for the booked room. Wrist bands would solve the pool problem. My stance would then change and to the OP I would have said "yes your guests are welcome".
OP, sorry if my and others posts have offended. I cannot say that you are going to bring your guests to the pool.
Now someone stated that maybe I'd be happier owning my own condo or house where I can set the rules. Fair enough, but I bought into a program where, call me crazy, I did not foresee dealing with pool hoppers and hoards of "guests". I follow the rules as stated and I guess I expected others to also.
Maybe those wanting guests are the ones who should have bought there own house or condo not me.
