Goa ?

My husband is 50yr in December and I know would love a trip to India. Everybody seems to be suggesting Goa as he is vegan, I'm veggie and they seem to think that this is the safer 'bet' When's the best time to go?

Should we go all inclusive or bed and breakfast as we have heard that it is cheap to eat and drink when there?

Thanks (small international traveller of Barnsley, South Yorks!)
