Just to add - Parking 1 is residents only. Visitors need to use the Retail Parking. Just drive along the front of JBR Murjan section ie do not turn into the service road but turn right at the traffic lights ( Fish& Chip shop/Avis) the parking is signed from there up to M level.
Please note if you are coming this evening in 2 or 3 hours it will be chokka on that road!!
exit off Junction 32. I think you need to follow signs for Al Soufouh. (You are heading towards the Westin Mina Seyahi). Turn left at the traffic lights. Go over the bridge. Marriott Harbour/Grosvenor will be on your left. Take the first service road turn on your right. Parking 1 should get you into Murjan 4 car park - I hope! Good luck.
