==== 19th DIRAC Working Group Meeting 2016, Odense, May 29th - June 1st (Arrival May 28th) =====

==== For new people ====

The DIRAC meeting is a family reunion for DIRAC developers and
DIRAC friends. It is a nice opportunity to meet the people behind
the DIRAC code. There is no registration fee but for organization
purposes please let Hans Jørgen know that you want to come.

Most people will stay at the campground (more info below). The cabins are very
good comfort, not expensive, and it's fun to be there. Book them well in advance.

We will discuss science but a significant part of the program
is reserved to discuss the future of the DIRAC code, programming,
code maintenance, release planning, as well as for programming task groups.

The meeting program is self-organised, simply add talks and
discussion points to the program.

==== How to get to Odense ====

Typically you will fly to Copenhagen or Billund and then take the train.
From Odense train station you can take the bus or share cab to the
[[http://odenseuk.dcu.dk/|DCU-Camping Odense]].

==== Lodging ====

Make your cabin reservation at
[[http://odenseuk.dcu.dk/|DCU-Camping Odense]].
The cabins can accommodate 3-4 people so organize with others.
Use the dirac-developers mailing list.

**Present reservations**

   * old-style cabin U6: Trond and Luuk

==== Bus tickets ====

  * Fynbus web page is [[http://www.fynbus.dk/?lang=29|here]]
  * regular bus tickets cost DKK 23 for a single ride (including changing lines) and are valid for 1 hour.
  * alternatively you can "rent" a bus card at the 7-eleven store at the train station (deposit DKK 50 + DKK 10 per prepaid bus ride with this card. E.g. you ask for a card with 6 rides, cost DKK 110). Using this card the cost for a bus ride reduces to DKK 10.
  * arriving by train you can use your train ticket for the bus and get a free ride (to the campground).
  * bus routes ([[http://www.fynbus.dk/find-din-rejse/rute,20|line 21]])
