For a tourist, Macchu Picchu is a whole different universe than Guatemalan hinterland, which is mentioned as a Wendi-thing ^^^. The first requires an expensive guided trip, and you do the climb with hundreds of other wealthy folk in spanking new LL Bean outfits. Totally sanitized experience. You can't go without a guide. All controlled.
Guatemala, on the other hand, is rough around the edges. It's more of a "Lonely Planet" niche. A beautiful country, but a visit to most places would be in the "developing country" category. Everything a lot more rudimentary. Definitely not Costa Rica (which we know from Caitlin Armstrong's criminal escapade). Antigua may have some expensive hotels (dunno), but, if you'll notice, you don't really see ads in expensive travel magazines for vacays in Guatemalan hinterlands. "Yoga retreats" at Lake Atitlán, maybe, but these seems kinda loosey goosey, though they prolly charge alot.
Guatemala has had a history of guerrilla movements. Peru is a rough place, evidently, but the Macchu Picchu adventure is very controlled, and it's one big site. My impression is, in Guatemala, you're pretty much on your own as far as planning a vacation, and the amenities are unlikely to be on the posh side and maybe not always comfy. Very rich experience, though. (I have been there, including to Antigua, but not recently).
We know Lake Atitlán and its "developing" context from the recent case of a drowning there, where I think family and millions of internet posters seem to have been shocked that the authorities in Guatemala and the services there, might operate differently than in the US.
It very much surprises me that a Wendi-type would be going to Guatemala. It doesn't seem like she'd tolerate any kind of discomfort. I could see Jeff going there, though.
Here's major MSM on Guatemala to give an idea. Note: Antigua is not at Lake Atitlán, though it might seem so from this article. IIRC it took us many hours to drive from one to the other. Haha...."luxury hotels"...this may be relative to other places in Guatemala. Oh, I see, it's pretty much a nice B & B on Lake Atitlán.
Adventurers flock to Antigua, Guatemala, for its proximity to lakes and volcanoes, but the historic capital’s boutiques, luxury hotels, and new restaurants are just as appealing.

FWIW I'd recommend going to these areas of Guatemala, if you have a chance. I'd go back there in a flash over Macchu Picchu. What was unforgettable for me was not so much the scenery, or the buildings of Antigua, or even the Mayan temples buried in jungle, as the local villages, Maya descendants, the markets, brilliant colored woven costumes. Chichecastenango, Quezaltenango, Sololá...Loved it all. One of the most striking experiences I've had abroad as far as the richness of local culture. I remember it being very hard not to stare at the locals.
