Yeah, sites demanding a roundtrip for every small interaction can be a pain to use when traveling. The principle I'd wish more web devs would keep in mind is, "Just because the client managed to contact your server once doesn't mean it will have fast and easy access to it in perpetuity." Indeed, in my experience, too many roundtrips is the cause of most atrociously slow websites, regardless of how heavy or light a framework they use.
