It was the first slot offered to my class and it dropped to the bottom half of the group - ie not many wanted it. The pair that went enjoyed it, but started PT in STL, flew to Paris for MT1-7 and Loft 1 &2, then flew to DEN for Loft 3 and LOE. Seemed to me to be a lot of travel for little gain (they had maybe 2 days where they could explore). They also were flown to Paris in economy (but got upgraded on the return YMMV).

Personally, I would pick the slot with the best footprint for you. If that is Paris/Finland so be it. You'll have plenty of time to travel while you await IOE.
