Hi Ted - I'm doing an Oly on 19 May, another on 4 June, and a half-IM on 10 June. Then 2 weeks rest.
The start numbers and swim groups are not up on the site yet, but as sm said, the women (and all the pro racers) go in group 1, and the relay swimmers are in the last 2 starts. All accommodation in the area gets booked up a long time in advance so I'd start looking now if I were you. I know people who go year after year just to watch!
