Why Goa? It is very far from Scotland. And if you are flying this far, better that you go to Thailand .. Phuket
If you are a well adjusting foreigner who likes surprises come to India .. if you like life to be predictable, neat and clean roads, good tourism culture .. go to Thailand. Thailand is a far better destination than India for a tourist.
You will either absolutely love India or absolutely hate it .. 100% either way no greys .. Phuket is a better bet.
Watch the 16 part vlog I posted for an idea.
To be honest Phuket is better not just a better bet.
