Wyndham Garden San Diego - Rates from $24! (early 2017 dates)
I'm seeing a rate of $24.11 for the 2 Doubles Sofabed and 1 King Sofabed room types on Priceline for some dates in early 2017! I even see a Family Suite with a King and bunk beds (on the 29th, for example) for the same price. A 2 Queens and accessible rooms are showing for just over $32 per night as well!
Why not book one of these and see what happens?
Free Cancellation: (your credit card is charged at the time of the booking)
Sample dates: 1/6, 1/17, 1/29, 2/3, 2/21 (I only tried these dates, so you'll want to search for others!)
