Evita, are you going for just one day? Since it's an indoor tournament, you shouldn't need to bring much. A camera and a water bottle for sure.
If practice courts are available to fans, try to do that. It's a good way to get an up-close look at the players.
Thanks for the advice. Yes, I think I'll only attend the tournament on Thursday but I'll stay in NL until Sunday. Maybe if I like it very much I'll try to get tickets for Friday.
Oh and Andreea, thanks for your advice too
