Dear Megan,
I hope you had a great weekend.
You were a big help to us for the last 4 years since I first contacted you regarding booking hotels for IDS.
If it weren't for your assistance, we would have had a hard time to make the show successful.
We went back and forth a lot and thank you for your patience and understanding in advance.
I appreciate our collaboration and getting to know you.
Hope you have a great day and start to the week.
With warmest regards,
Phillip
