I have been before- and personally would not reccomened bulgaria.I personally prefer Switzerland as both the hotels and the food are of a better quality.Also, the pistes are generally better groomed etc..
Give Switzerland a go.
We went to grindlwald in a lovely luxury chalet with a personal outdoor jacuzzi.
Spending money ,i cannot remeber sorry, we seemed to live acceptably on around £100 a day ( for 2 of us)
You cannot compare the quality of life in bulgaria to good old switerland.Dont shoot the messenger- I am just saying that overal switzerland has a higher quality of life/better infacstructure than that of Bulgaria.My wife and I love Swizterland, for both its beauty and the luxuriuos private chalets.
