I took DD on our first ever trip to DLRP last Feb half term - we were the week after you Leanne I think. We also went midweek.
I was surprised that the park wasn't really busy. Although by about noon each day, Fantasyland did get very busy, and there were queues for the rides (longer than we wanted to wait anyway) for everything except Its a Small World.
The weather was milder than I expected, even sunny on our last day. It only rained the whole 3 days we were there for about an hour one morning too.
