I agree with PP, Saucers line will grow fast so I'd do that at RD first. We did not get a FP for SDD and we RD's SDD and waited 15 min after arriving at DHS at 8:30am on a 9am park opening day (this past Nov). Then we rode saucers, maybe waited 25 min for Saucers but by the time we got out of line the saucers wait shot up to 60 min then did TSM FP+ after.
