They have bell services, yes, just not valet. When we pulled up, there was someone at the bell stand outside VGF and he asked if we needed assistance with our luggage. Ours was already in storage since we were moving from BCV, so we didn't, but I assume he's the one who would've contacted the main resort.
Um, it's not separate. I guess to answer your question. The bellmen are all from the main resort, but there is a small bell desk at VGF. When you hit the "bell services" button on your phone, you're calling the main desk at the main building.
