We could all go on at quite some length about how the various chains and families of brands compare. But there are already countless threads across multiple forums doing that. If I were planning a 2-3 month stay in a single hotel I would certainly consider various brand-level factors but it'd also be critical to have knowledge of the particular properties I'm considering. That's because even in chains that have a high degree of consistency across properties there are still variations between them. In every portfolio there are at least a few stinkers as well as the occasional gem.
