Thanks for the ideas everyone! I rechecked my budget and we have closer to $500 set aside. I hope that sounds a little more realistic because we're definitely planning on working Tikal in.
Does anyone have any names of tour operators they recommend? We're staying at the Aguada and hear that they do some great tours but I didn't want to miss a great tour guide or company out there.
Thanks again for the great ideas. I love the idea of exploring some on our own, minus the tour guides. Great way to save money and have our own adventures too!
