From what I have seen of VKO fees, your best bet would be to make an even trade: Fees for the Cirrus and an airline ticket West. I, too, have gone back to hotel after a six-hour wait for a trans-Atlantic clearance. But, OTOH, I "turned" VKO last month in 1+20 which has to be some kind of record!
Can't say as I have ever seen a Cirrus-category plane at VKO III, just sayin'
