I would like to ask someone if he is a globetrotter (someone who travels a lot). I would like to know if there is an expession in Esperanto.
If you just want the meaning of someone who likes to travel a lot, I recommend vojaĝemulo because it is formed out of common Esperanto suffixes and it’s easy to understand for any Esperanto speaker, even if they’ve never encountered the word before.
You could use mondtravaganto (or mondotravaganto for easier pronunciation) or just mondvaganto.
In case you need a reference, search tekstaro for mondvaganto.
