Monty mentioned this training camp in the comments to a post several months ago, and after much dithering and delay I've just booked. Somewhat to my surprise there are still places available and greater flexibility than originally over dates, and Emma's still expected (though not absolutely guaranteed) to be there. Budget flights are getting more expensive every day though.
Now, time to get in training for the training camp...
UPDATE 1 March:
Email from Tim says Emma will be there from 24 March until 6 April. And there are still spaces for a few more people, particularly during the second week. Tim says he aims "to give everyone opportunities to ride with Emma and to get coaching time with [him]".
