Has the A&E meet and greet (by way of FP+) started yet? If so, then there should be some feedback available as to what RD is like there. If it hasn't started yet, then we simply do not know what RD will be like and I would hesitate to take TP's advice on this because the folks there are just guessing at what the situation is like for RD'ers. Since every single slot is being booked in advance (other than perhaps some that are held back but will be gone within the first 5 minutes of the park opening), I am not sure how much room will be left for SB people to wiggle in to the line. We might be looking at a situation where the meet and greet is FP only. One option would be to keep your FP, arrive at RD and head straight to A&E. If the wait is not too bad, you can do the SB route and exchange your FP for something else. But I would hold onto that FP until you see reports here or elsewhere that reveal that arriving at RD is a viable strategy and results in a wait of 30 minutes or less. But frankly, I just don't see that happening unless you are literally the first person through the tapstile that day. Even then you could be in trouble. AT Epcot, the people who had early ADRs at Akershus built the line up to an hour even before RD. At the MK, you will have all the people with early ADRs at CRT and Crystal Palace. The total number of people with early ADRs at those two restaurants combined will dwarf the number of people who used Akershus as their path to A&E success. With the Mine Train set to open, and A&E moving to the MK, the pre-opening ADRs at CRT and CP will become the "next big things", even more than they already are. All those sullen fathers who have been holding spots in line in Norway are simply going to shift over to the MK nullifying much of the benefit of RD.
