Ha ha, no offense taken! Well, we'd be remiss if we didn't recommend the book of our colleague, Al Argueta:
Moon Guatemala (
http://fr.moon.com/books/moon-handbooks/moon-guatemala-second-edition).
It's been a couple of years since I visited Guatemala, so I haven't read the book. But knowing what Avalon Travel Publishing puts us through to ensure Moon Nica is of good quality, I feel confident Al has written a great quality guidebook.
Happy travels -
Randy
PS - Nicaragua is safer than Guatemala, boo ya!
