How much of a hassle is it to get from the hotel to Central? I have an upcoming 4 night stay and booked 2 nights in Central at The Pottinger, then 2 nights at the RC to detox and check the hotel out, but should I decide my detox plans were a bit hasty and want to get back into the thick of things, is it a major project? I seem to recall the hotel being a bit tucked away.
