Interested in the area but difficult to tell from piste plan which village makes the best base. Criteria are to be within walking distance of slopes, mainly for DS (5.5) who will be on his 2nd skiing holiday. Would prefer to arrive by train so not the option of driving to a different slope each day (ski bus any good?). Prefer 4* hotel with pool. Having said that like the look of the very modern Haller Hotel in Maria Alm, any views? Do any of the villages have a good indoor pool.....sorry, just a whole list of questions really.
