I'll be heading down KL once again next week just for a short getaway/break from my busy work schedule and due to the tight schedule i have, I only have 2 days available to enjoy there

Thus reaching Friday morning and leaving Saturday night.
Will be flying there by JetStar, arriving KLIA early in the morning and then proceed to Times Sq (most probably) for check-in. First time taking plane to KL haha due to the cheap price offered, it's almost the same as coach fare
Anyway, what other nice , good shopping areas around Bukit Bintang or else where ?
The above mentioned like go until sian already

thou, I've never been to MidValley which is pretty out of the way but my friends say also nothing much, not worth to wait in the jam and waste almost 1/4 the day traveling to & fro there.
Was wondering any other nice shopping places ?
My itinerary actually shop as much as possible with my GF after check-in, till as late as possible, then next day go for some nice Spa/relax before we go back to "sad SG" again..
Lastly, anyone know how long's the journey and price from KLIA to Bukit Bintang via cab ?
