Take your time here - much time. As much as you have. The Bedouins here recognise any tourist staying longer than 1 day. They are amazingly friendly. Wander through Petra without a map, just taking in the scenery. Be open to be invited into cave flats by very poor but incredibly hospitable families. Have tea with the Bedouins and don't be shy to ask questions about their lives, culture etc. They are more than willing to answer. The days in Petra (5 altogether) belong to the happiest travel memories ever and I've got many good memories...

The ancient city of Ayuthaya are a must for any visitor to Thailand. Even for people without knowledge of Thai history (such as myself!) it's a great place to see. It makes for many great pictures, especially if you go there later in the afternoon. The soft light makes the ruins look mystic and takes you back in time. It's a stunning sight.
