In all honesty, lounge around the pool, as far as I am concerned. Abu Dhabi is trying to catch up with Dubai and now has the only satellite of the Louvre. It also has Ferrari World and the Sheikh Zayeed mosque which is stunning for the workmanship in it alone. You could also stay in the $3,000,000,000 Emirates Palace ( which is currently on offer! ), one of the most opulent hotels on the planet.
What do folks do when they go to Abu Dhabi ?
Ok. Drive there?
Also worth a look at skyscanner as sale prices seem to be available a bit cheaper there
£330 for a 6/7 hour flight isn’t a good deal imo
