Thanks for your reply. Yes, 4 days is a lot for Doha but I wanted some pool/spa/relaxation time also since I'm coming from a busy situation. I definitely plan to go to the Islamic and National Museums, plus Souq Waqif, even though I know it will be touristy. I will go to the Villagio Mall since it's recommended and the Msheireb complex of museums and possibly to one of the heritage locations outside of Doha, but I think the heat may be too much for those, unfortunately. I'll keep an eye on what's happening at that time. I'm staying at the JW Marriott in West Bay.
