We did the same, we stayed in Maldives for the 1st ten days, then stopped off in Dubai for 4 nights on the way back. As you can imagine, after spending the first 10 days in absolute Paradise I was dissapointed to arrive to the worlds largest building site. Though
once we arrived at our hotel in Jumeirah all was ok
(apart from being the end of the footy season, and every premiereship footballer and his dog (literally) were there)
We mostly chilled at our hotel complex in Jumeirah (Madinat Jumeirah, which has everything, and you can use the facilities of the Burj 8)). Though we did do the desert tour, which included dune bashing in a 4x4 (absolutely brilliant) folowed by a camel ride (a bit smelly) then a BBQ and a good ol' smoke of the Shisha, I highly recommend it.
I wouldnt bother with the Gold souk, now with the price of gold it just isnt worth the traffic jam to get into town
The shopping is great, I got some nice new suits at amazing prices, and 'she' got some nice shoes apparently. And you can ski if you like at Ski Dubai (her indoors wouldnt let me), its weird to see the Arabs skiing past as you shop
As for eating, I cant recommed highly enough the restaurant on the pier in Jumeirah (if you are staying in the area) called pierchic. Tea at the Burj is quite a stuffy affair, though is worth it for the view.
Apart from that mate, I cant really say much more
Ps Am I right in thinking you have something to do with Liverpool one ? If so is Bridgestreet at Liverpool one ok to stay at
