Subject:  Request to Attend the National Conference on Addiction Disorders 2018
 
Dear [Decision Maker Name],
 
The National Conference on Addiction Disorders (NCAD) takes place from August 19-22, 2018 at the Disneyland Hotel.  NCAD is the premier, respected, and trusted national conference that provides a diverse educational curriculum on the prevention, intervention, treatment, and recovery management of addictions that affect various genders, generations, and cultures.
 
I would like to request approval to attend this conference, as I believe it will not only keep me up to date on the latest research, case studies, and methodologies in treatment, but also give me practical, “put-into-action” takeaways that I can then share with my colleagues.
 
If I attend I will have the opportunity to:
  • Earn CEUs
  • Learn from a diverse curriculum that includes hot-topic areas.
  • Re-energize myself professionally through networking.
  • Experience NCAD’s important Gender Matters track.
  • Stay ahead of emerging topics that reflect today’s headlines.
  • And so much more.
PLUS, the conference registration fee includes coffee breaks and lunches.
 
The approximate investment for my attendance is as follows:  
Travel costs
$300
Accommodation (4 nights at $224/night*)
$896*
Dinners (4 days at $25)
$100
Supersaver (before 3/21/18) Delegate Pass for 4 days
$450  
Total cost to attend:
$1,746
 
*NCAD has this specially negotiated hotel rates for attendees. 
 
When I return from NCAD, I will compile a short presentation covering speakers’ presentation notes, useful vendor product information, new contacts made, and a proposal for implementing new ideas that will benefit our team. I will also make any conference materials available to my colleagues.
 
To benefit from the current supersaver discount, I need to register before March 21st, so I appreciate a quick response, and I thank you for your consideration.
