Pompeii

I'm looking at organising a surprise trip for my wife and daughter to Pompeii. It appears to be top of their want to go to - places.

Has anybody visited Pompeii while having a beach holiday not too far away? Although they want to go to Pompeii, I know the wife is a bit stressed and would benefit from three or fours days on a good beach in a good hotel but as I mentioned, within easy travel of Pompeii.

Any hints, tips and recommendations would be much appreciated.

Thanks in advance.
