If you fly from Frankfurt/Main to Las Vegas directly, you can use Condor for around 730 Euro non stop!
Registration started for the Xojo Developer Conference 2014 in Monte Carlo Resort and Casino. So you can already take the chance to reserve your seat. Be sure to take advantage of the early bird offer: $750 until November, 30 2013. Regular price is $950.
Also the hotel has an excellent rate. Looks like it's $69 for some days, but if you stay a week you are at about $77 in average.
The Xojo developer conference is the biggest event in the year for Xojo developers. Usually there are about 100 guests, but maybe this time a few more due to being in Las Vegas? See you there next year!
