Long time lurker, first time poster. I'd like to start by saying bravo on this amazing community you guys have built. It's inspiring seeing all the people here, contributing and helping people find their way through the complexities of investing.
I'll make this as brief as possible. My wife and I are both 32 and quitting our careers next April to travel the world for about 1 1/2 to 2 years. It was this, or get locked into a mortgage at 32. We decided the mortgage can come later

We currently have:
$220k in the bank, stupidly earning like .001% interest. (will have about $250k after we sell the cars)
$52k in taxable, individual stocks (Apple, Google, Netflix, Tesla)
$32k in IRA Vanguard lifestyle growth fund (during our year of travel making no income, it was recommended to look at converting this to a ROTH IRA)
We are setting aside $65k for the trip.
Leaving a $50k nest egg for our return to float us while we get back into our careers (which we aren't expecting to take long)
Hoping to invest $100k-$130k in something that will "work" for us while we are gone. It's actually my hope, to let this be a basis for a retirement fund that we will not touch and continue to contribute to upon our return.
I've met with a family recommended financial advisor. He put together a plan but my instincts and own research make concerned about his plan.
He wants me to invest about $80k in REITs and $50k in American Funds. This does not seem like sound investing to me. All the REITs are new prospects with no historical records therefor to me, seem to be extremely high risk. And I've been reading terrible things about American Funds and their high fees. Their brochure is amazing but upon further research it doesn't seem so peachy.
It seems many here are quite comfortable and happy with a Vanguard three or four fund portfolio as seen here viewtopic.php?f=10&t=88005. I realize this may be playing it safe and result in a lower yield, but it seems to make the most sense so far. I'm sure it's clear based on my verbiage that I'm new to this and I hope this doesn't come off as lazy, but I'm looking for advice.
Does this sound like a reasonable game plan? Does anyone have any suggestions or alterations I should make?
I've read over the other posts asking similar questions but I feel this career break we are taking puts a bit of a unique angle on the situation. Thanks in advance and I apologize if I'm missing any information or not asking this correctly.
