Get it sorted Melissa..... need to meet up with you both in the Titantic for paaaaaaaaaaaaaaaaarty!! Tell them you know that Disco Dave bloke.. that should work!
Don't worry. I was in Bovovets in the middle of Feb with BulgariaSki.
They didn't contact me at all prior to departure, but everything was fine. The flight tickets were electronic (you just turn up at the airport with your passport), and a driver met us at Sofia airport with a card with our names on it.
Make sure you take their Bulgarian office number with you, so you can phone from Sofia airport if there are any problems.
