Yosemite: Last Minute Bookings
Here it is Wednesday, August 5, and I just booked a room at Yosemite Lodge for the busy weekend August 15-16. It's an example of how room availability tends to open up even during peak season as the "7-day-in-advance of arrival cancel without penalty" date arrives. For the last month I've been checking but no space has been available, and then suddenly it was.
Booking early, as in 6 months out, is one option, but then the other option is just to wait until 10 days or so in advance of arrival.
For the record, a larger party must have relinquished several rooms, as there was still space available after my room was booked.
