Back yesterday from a brilliant weekend - thanks to all you who posted on this thread - a great help.
To sum up my tips/comments:
Food / Drink : nowhere near as expensive as I expected - stayed away from main tourist spots when eating.
Carnival : Excellent - we had no idea when we booked it...
Taking advantage of no game and going there this weekend.
Arriving at Marco Polo Airport - what's the best way into the centre please?
Any other must dos/must avoid....
Thanks
