Many have offered hospitality to him over the years. Lloyd has stated repeatedly that he wanted to visit LA again - a probable sign that he enjoyed the hookers on the Sunset Strip last time round.
Pure speculation - what if what set off this summer’s meltdown was his realisation that there wasn’t anyone out there even remotely close to the relationship he ended? He starts making overtures towards her about reconciling, only she wasn’t having it. Perhaps even revealing that she was already seeing someone and that they needed to move forward with the divorce.
Having no luck with the Zagreb crowd he was trying to cozy up to and likely being turned down flat once the prostitute addiction became known, he tried to re-kindle something back home.
Yet another lonely holiday season, so he flees to LA for some action on Sunset Blvd. Thus the need for the hotel room instead of a room in the home of his patron.
