Well, when my Yosemite traveling partners said they had booked into a Best Western, I was initially concerned because I generally avoid this chain. However, I was quite delighted by the manicured grounds (the place almost looks like a low-brow resort). The room was spacious and comfortable, although I noticed some spots on the blanket. Breakfast: very generous, lots of food, but not that great (I'd rather have one good pastry than a plate of mediocre food). But most people were loading up their plates, and seeming to enjoy it. The staff was generally friendly and accommodating.
One caution: this motel winds up a steep climb. If that will be a problem for you, be sure to book lower-level rooms.
