Western, Western, western & western. Those are my choices in that order. I don't dislike eastern, but if I had the choose one over the other, no question western.
BUT, it really depends on what you like. If you like to spend time looking at the scenery, bargain shopping for jewelery & perfumes, and relaxing, go eastern. If you, like myself, prefer more action, watersports, beautiful beaches, junk shopping (t-shirts, chatchkis, liquor, blankets & hammocks, etc.) more activity and nightlife, definitely go western.
