Save your money and go for a late deal, can see where the best snow is. Alternativly book Banff or some US resort, hubby was skiing in states in late may and snow was brill, season didnt end until July!!
Jo,
Forgot to mention, if you are considering lapland, be aware of the price of alcohol, its very expensive, £6-8 for a beer!!!. Still you can always spend the evenings gazing at the northern lights from a hottub!!.
