The Parramatta RSL CC launched their 2007-08 Australian Chess Championships website a few days ago. It's simple, clear and looks to have all the basic info needed if you're considering playing in the event.
One thing you'll notice is the odd schedule with the first half of this event being quite demanding. Then we slow down to a rate of one game a day from round 6 onwards. That's understandable really as it speeds up the event but also caters to the tougher fights in the business end of the tournament. However, I have to say, the 10.30AM starts are a bit early.
Also the featured hotel on the website, the Marriott Parramatta, strikes me as a bit too pricey for the average chesser. $115 for twin share! Now I don't know if there are backpackers in Parra but there are plenty in the Sydney CBD. I'd suggest looking at those as options. Of course, if you're more the premium type, 5-star and all, then you obviously can't go wrong in the city. Whatever you choose, you'd be playing chess in Parra then heading back to the city's nightlife at day's end. You almost can't complain.
While the playing venue itself may not be to flash, Parramatta is a lively multicultural town with plenty of shopping and eating! You'll have plenty of fun.
