Been to boro many times and love it, lots of places to eat, good bars and great skiing, went to Bansko last year and was'nt that impressed, the lift closed for a coupke of days and so could'nt ski as there is no other way of getting to the slopes, the night life was a bit poor, Borovets has a great atmosphere, we going to Pamps in January for first time, fancied giving it a try for a change.
Phil,have been to all three all have there own plus ,however Boro and Pamps are resorts and there for have a little more to offer,So imho try Boro and you won't be disapointed .But you will go back to Pamps again and again.
Great to be back thinking about sking again ,and good to see this forum is as lively as ever.
