We are going in February for our second trip to Disney. The first time we had a barely two year old and 6 and we primarily did character meals. We got free dining again this trip, but we wanted to do some different types of meals. So we are planning on HDDR. When I tried to get an ADR last night they wanted an upfront payment. Is HDDR not on the dining plan? I thought it was two credits. So confused about how that works.
