Just to confuse matters, I’m going to recommend something completely different 🙂
Why not combine a ski and sun (and possibly even MTB) holiday in Spain? I believe Motril is a good base for MTB and is less than 1 1/2 hours from the Sierra Nevada and similar distance from Malaga for cheap flights.
My in-laws live a couple of hours from Sierra Nevada (Spain, not USA), so I took my lad up there for a day. Granted kit hire and ski passes for one day is not cheap, but it was a good taster for him in Easter sunshine, whilst off the mountains it was shorts and t-shirt weather. It’s not a huge resort, so probably won’t be enough for good skiers over the course of a week, but if you want to take your daughter for the proper mountain experience and some beach time and potentially some MTB, it’s worth considering.
