You are absoloutely welcome to come down. While I cannot garuntee a table every second you want one, you will still be able to probablly get 2-3 games in. Things usually calm down after 9 so after that you'll be good to go without a problem.
Also, many regulars are not in the league due to the limited spaces. Just trust me that it will be worth the trip. This week, there's a 50/50 chance I'll be there to help you find a game, TRUST me, I'm hard to miss. Otherwise talk to Nick or Ian, I'm sure they could help you out.
