What is Morris' advice to Philip regarding his conference?

Morris sympathizes with Philip about the low attendance at the conference, but also says that if the food and accommodations aren't satisfactory, people will not be able to concentrate on the conference matter. He cites conferences he will be attending over the summer, in Amsterdam, Jerusalem, and Zurich, as travel destinations people want to visit; he also adds that most British universities don't limit international conference fees as they do domestic ones, so people are happy to travel to somewhere warm and inviting.
