hey westy and jblack, skip flores and ride straight to the entrance of tikal there is camping and a couple hotels there. i assume that is on your route and has to be one of, if not, the best of the popular pyramids ruins down in that area. staying at the entrance offers the chance to enter the park before the visitors from flores show up. there are also some great paths and roads which afford a walk through the jungle to access the temple complexes which for me made tikal unique over the others [of the popular ruins] i visited. also if you end up at palenque, stay at one of the many guest house at the entrance and ride up to the ruins. they are a couple miles from the entrance. try and find the T shaped door in the complex. it has architectural significance that can be traced all the way up into the south western cultures of arizona and new mexico. good luck with planing and executing your trip and if you have to skip something try to at least make it to tikal.
