Yes, it is usually around 3, but this last trip it was almost 4 before our room was ready.....I would think 4:30 would be a safe time....in all my trips to WDW, this was the first time our room wasn't ready be 3 - never stayed at WL before, so don't know if that is common there, but isn't at the other places we have stayed.....we were so anxious to check in....had driven over 18 hours then went to the parks to play for several hours, so at 3, we were ready for showers, naps, pool, something...that extra hour was tough

...but the resort was awesome, so we quickly got over it.
