The crushes at some of the clubs mean you just can't dance...get to the bar etc. If you are a reasonably large number and can afford it - I would def book a table. However, some places like Ushuaia have tables right at the very back... I don't see the point if you are far away from the DJ/vibe. So always ask to look at the table plan and see what you're getting for the price. We took a large table this time at Amnesia for Elrow... it was def worth it.
