HI Silom Upgraded me to Club Room, an excellent property with first class service and a restaurant to match. The only bad thing is the slightly awkward location.
HI Ploenchit Upraded me to Suite with Club access. Busier property, classier, more expensive area, three steps to Sky Train. Nothing bad to report.
IC Bangkok Choice of Suite or Club Room, on the odd occasion both depending on who checks me in. Location as above, breakfast is worth looking forward to. Best concierge and bell boys in town.
New HI Express No plans to stay. Good value for those without PC membership or status I guess.
