In my limitted experience, that need not be the case. Such resorts certainly exist - e.g. Cancun, whose airport I passed through - but there is plenty of "unspoilt" country left. And the arcaeology definitely makes a visit worthwhile.
One trick is to avoid anything that is air conditioned (hotels, buses, taxis etc.). They will be full of Americans. Instead, travel and stay with the locals and many European tourists in the non-aircon establishments.
My main complaint was the agro from souvenir sellers inside the archaeological sites. In some places, especially Teotihuacan, they were very agressive and very numerous.
