Hi. We went last year as an add on to a trip to Canada. We stayed 5 nights, arrived mid afternoon on day 1 so we just did DTD and a character meal at goofys kitchen, then had 4 full days leaving mid afternoon on the last day. We did everything we wanted to as many times as we wanted to so I would say that's ideal (we went end of August so it was hot, reasonably busy and we caught the start of the marathon weekend which made Friday and Saturday busy. I guess it depends on crowd levels and how much you want to do. I would say a minimum of 3 days but 4-5 better if you have the time. Have fun, we loved it, especially Carsland (must do RSR at night!). Also found photo pass was a real bargain, lots of magic shots (look for Dave at the partners statue and also the photogs by Flos).
