Thanks Travelingjack04 and meijiem good to know. If I can apply my Amb cert at the IC will definitely move that stay to the IC, and then for my overnighter at the end of my trip will either keep the HI (have booked a King Suite for that one night as looks nice, standard room for the 3 nights at the start) or if I find I really like the area from the first stay might try the Indigo or Vignette

Thanks also for the restaurant recommendations and the booking reminder! Merito was mentioned already by a colleague so will definitely look at that, Maido also sounds good
