Interesting delimma. Personally, I would bring some weights with me. Bumpers, Bar, and two or three kettlebells. I would train when I could and keep it to cleans, pulls, snatches and drill work from the floor. Do the kettlebells for conditioning - if you can and have the steam.
Then when you're home. Do two a days - Bulgarian volume train, baby!!
That's me. I like volume and frequency. But I've seen powerlifters actually benefit from two week on, one week off training. But never two week on, two week off.
I would find a way to do something to maintain while you're gone. Kettlebells at the minumum. Portable. Easy to transport. Don't take up a lot of room. And very functional.
Don't know if that helps at all?
All the best,
Lifting heavy stuff is fun and relative......
