Hi Celia,
There will be 25 people on your holiday.
I'm afraid I don't have any info on coach pick-ups but you might be able to get in touch with any other travellers from the West Country through this website. They might see this message but you could also post a note on the message board, using the 'Get to know your fellow passengers before you fly' option.
Don't worry if you don't make contact beforehand. You'll be at Gatwick before you know it and I'm sure you will forget about any nerves once you've met the group.
Have a great holiday!
Kind regards,
Olly, your editor
