Haven't stayed there yet, but I have my eye on the Courtyard Anaheim Theme Park Entrance. It's pretty new, has a water park, bunk beds, and is across the street from the park entrance. Depends on what you're looking for though? We have kids so the water park and bunk beds would be awesome for us.
Room rates have been around $350-400 when I've looked, and costs 50,000 Marriott points. So an okay redemption. If and when I book, I'd probably debate a while using the Marriott points or URs with CSR, would depend if I had other uses for the Marriott points.
