on the basis you have had your car for a month now and will no doubt have maybe another couple of hundred miles on the clock before you go on Friday taking you to say c.1000-1050 miles, id get the run in service done before you go to Vegas. at least then, you can open the taps up for the first time on your roadtrip to vegas
id ask your dealer if there are any warranty, resale or other problems with performing the run-in service after 1650 miles rather than the recommended 1200...
