Normally start at 10, though some instructors are flexible and will start earlier, I have never had any problems with the ski school and always found the instructors helpful.
Hi
We went in Ski School last year in Borovets.
First 2 days was 10, but then we started to meet at 9 to try and beat the queue at the gondala.
Everyone seemed to have the same idea though.
Was a bit of a rush every day - up early every morning and rushing around. But we would have been no good without it as we were first timers.
Normally 10-ish but once we got to know our group, we tended to meet up a bit earlier to beat the gondola queue and "warm up" before school started. So early starts all round by the time you factor in your brekkie and meeting up, not good for hangovers!!!
