And congrats Phil on your team winning this past weekend!
I'm in the same boat - not enough vacations to go to all the nationals and team trials. This year, going to Orlando in June does not appear to be the most attractive use of my vacation time.
Martel-Stansby among others play a 3-way signal in this situation:
low - encouraging, but don't make attacking shift if A stiff
middle - encouraging, but do make attacking shift if A stiff

2NT forces 3♣ for signoff, or if bidding on, it shows 5Y + 4X GF, and none-low-high shortness.
For example after 1♦-1♥-1♠-2NT-3♣:
