Before he buckles down to the rigors of full time schooling, Prince George is headed off on one last European jaunt, accompanied by his little sister, Charlotte, who’s also staring down the commitment of preschool this fall.

The royal children (accompanied by their mom and dad of course, but we all know who the stars are here) will be traveling to Poland and Germany in the next few weeks. The siblings’ Eurotrip will start in Warsaw on July 17 and wrap up in Hamburg on the 21st.

George’s birthday falls the day after the minibreak wraps up and well…could there be a cuter photo op than the almost 4 year old blowing out candles against a German backdrop?
