The Gulf of Finland was a seperate situation which resulted in a bit over $2000 (10% FCV). We also got nearly $4000 for cancellation of an extension even though it had been paid for with a voucher. Bornholm was Bornholm specific as I said: "We are sorry to hear you were unable to experience ----- ."
Yeah -----'cause they're so responsive to genuine issues brought forth here.
As to your "assuming" snark ----- I can supply a copy of the advisement (FCC 2188338 ).
Mariehamn having already been removed from the itinerary bolstered my whine - not to mention the whole Gulf of Finland. Maybe I just caught a sympathetic agent on a good day? Also got after them about a toilet issue one morning - another $1000.
PJS is really nice: extra room everywhere (including shower) - two sinks - extra TV so you don't have to sit on the bed and/or crane your neck (very welcome) - "free" laundry - etc. Whether the extra cost is worth it is your call.
