There's a fair dump of snow due on the weekend,lot's of people been put off by early conditions last year,as soon as it snow's heavy the prices will rise..
How about an easyjet return flight Gatwick - Sofia for less than £60 return (various dates in Jan, Feb and March), airport transfer around £50 each way between 4 and an apartment for £230 for the week
= less than £145 each with flexible arrival and departure dates
Early january deals are looking tempting though, as long as i book something and theres a bit of snow. I quite like the local beer as well - bargain price too.
