Just back. Happy to report CL at BC had new room keys. tey are still gold, but BC has gone to a new swipe system. It's very similar tot eh old system, but the new keys don't have to be inserted like before, you hold them in front of the card reader. They are also a slightly different color from the old room keys.
As for the greeter expereince. My luck has been about 50/50 on getting a front door greeter. It's not likley to happen if you arrive via rental car.
Also, I've ogttne conflicting messages on checking in at front desk vs. upstairs at different resorts. Generally, you do go to club level, but there's no reason why front desk can't help yo as well. The way I see it, CL gives you more options. There are times when talking to the front desk is easier, and many times when talking to CL is easier. I don't think it's helpful to impy that CL guests should never use the front desk as an option.
That said, if you wish to cancel/change dining- you should talk to CL staff.
In my experience, CL rooms don'ttned to be ready early. I'd guess that CL guests are MOST likely to request LATE check out, even if they have to pay for it. Even if your room is not ready, you can still sit in the lounge.
One more option if your room is not ready- consider the pool area locker rooms. You can get a locker (sometimes free), take a shower, change, etc. I was pleasantly surprised this trip to discover the BC locker room, located in the hotel gym. It was right off the pool area, and had free water-cooler water, nice lockers, a hair dryer, even shampoo and conditioner!
