2-3 RCC visits a week for me...useful (when on UA flights) but other than SFO and DEN there are no domestic clubs in the system I really look forward to using (I do really like some individuals at some of the stations - but that is another matter).
Due to the fact that UA has amazingly still not killed off the whole DL CRC arrangement, post-May I will be taking great delight in using my now dormant - at least in terms of flying - PM account to get access to both UA and DL clubs (and more importantly drink Leo's booze gratis).
That $300 will be better spent on my nifty new NW WC (and thats' not in water closet) membership...not towards re-upping.
We'll see if UA makes it through the year before I shovel any more $$$ their way for a club membership.
