If you get to the Yastrebetz Gondola in Borovets (after 9:45am), and find the queue is from the building entrance out to the gate at the road, don't waste 40 mins queing plus 25 mins on the gondola. You can be skiing in 20 mins if you take a taxi over to the Yastrebetz Express 4 man chair lift (over to the right as you look at the piste map) As with every taxi ride in Borovets, it'll cost you the grand total of 10 levs.
