We're arriving August 30 for 3 nights and I'd like to stay at an inexpensive place preferrably w/private bath. I heard Ruby's is great, but I also heard about Tomas Hotel that sounds nice & even less expensive. Do I need to make reservations in advance or can I just show up & decide then?

Also, is it worth doing tours to both Altun Ha & Lamani? I'd like to do both, but not if they're very similar tours.
