I've read all the info. re: VIP lounge a good idea when departing Varadero IF there's a huge line-up.
My question is, if I keep $100 in Cuban $ ($25 each to depart, and a possible $20-$25 ea. for the VIP lounge) but the line is short and I don't need the VIP $, is there a place to exchange back to Cdn. $?
