SuperDry, OLC should not have to be concerned about that. Besides, if you already have a Suica/Pasmo, then what difference does it make to load a 4-day pass onto it , or just charging your card to use on any days and times? Your uber cool idea seems redundant to me. Also, As far as I know, people staying at the official hotels (Miracosta, Ambassador, TDHL) are still getting the free DRL passes for the lenght of their stay, is that not the case? All other guests not carrying a IC card can still buy the individual tickets at the machine, which as you know is an inconvenience that takes only seconds to do.
In fact, for guests who are visiting for 2-4 days in a row, it's more convenient to buy the multi-day passes as opposed to using a Suica, because it would be cheaper to do that way.
