Welcome to CRT! First trip - I'm excited for you brother!! I still get goosebumps and butterfly's in my stomach every time the flaps go down as the plane is getting ready to land!!! Disneyland for men!
+ 1 on Puravidatransport or OneLuckydog. It just nice and easy to have a gringo waiting for you with your name on a card on arrival. You will be getting in late so HDR is an easy option for first night.
I wouldn't stay at HDR myself, but for your first night and hour of arrival....it might not be a bad idea! Plus you will save time and cab fare to and from the SL or LA.
After first night I would stay at SL for first trip. Both HDR and SL are bucket list events and rights of passage for Mongers!!!!!
Plus, the energy level at the HDR will be cranking at 1am versus arriving at SL or LA where it is quiet and dark and everyone is asleep....you might want to just crash for the night and not hassle with catching a cab solo to HDR.
But if you roll into the HDR......yahoo!!!! Plus there will be some gringos to chat up.
Good luck and write a trip report!
