Context: And then a few of us slipped out early to set up the picnic in Princes Street Gardens . The catering was done by Valvona and Crolla , which is apparently the best deli in the UK - and I believe it , because everything was SO good . It was nice for all of us to be able to share one big picnic together - I think it 's the only meal we ' ve eaten together since the first night here .

Option 2: The park gets crowded as the day goes on .
Option 3: They wanted to be the first so they could brag .
