Hello all.... our pool is complete!! and yup now we wish we added more sleeves we only want them on the deck (acrylic lace/kool deck) and wondered if anyone has added their own ??? I see they have the same ones we already have on Amazon cheap and wondered if anyone has drilled their own hole to install them and if so what size core bit did you use or should we just suck it up and get a stand for umbrellas
