I'm now back in the chaos/mayhem/madness (delete as appropriate, but all apply) of Hanoi after my couple of days on Ha Long Bay.
The reality is that, taking into account the four and a half hour bus journey there and back, it was about 24 hours actually spent aboard a junk cruising around limestone karsts (this did include one night). My experience was good and it was well worth it, but frankly one limestone karst is very similar to another!
The actual 'cruise' experience, rather than the geography, was the thing that was interesting/amusing/annoying (again all three adjectives applied).
First of all were the meal times. We had 3 meals on board - lunch, dinner and a late breakfast. The food was pretty good with, understandably, a heavy seafood focus. However, I sort of expected some kind of communal dining experience with everybody around a shared table so that you could actually talk to a variety of people. But no, as there were two single travellers we were expected to eat together on a table for two. Me a (very) late thirties Brit, her a later middle aged Canadian from Ottawa. Not a great deal in common beyond travel!
Thankfully by dinner time I'd got talking to two young, female English doctors, one at Southampton General Hospital and the other currently living and working in New Zealand (friends from Newcastle University, holiday sort of in the middle). We had much more in common so we made a table of three for the rest of the meals. The Canadian had hooked up with a group of three other Canadians who were retirees.
The next thing that was interesting was that of our group of 14, 2 were vegetarians and 1 was coeliac. How the hell do you survive in this part of the world with 'strange' eating preferences/disorders?
The final thing of note that was amusing was seeing Americans play up to my own personal stereotype. The couple in question were on a 3 day/2night cruise, so we saw them when they'd been out on the bay for a day and a night already. Talk about loud, and in the case of the woman, dumb! One of the other people in their group was giving them an iPhone tutorial which was comedy gold. Stupid people and technology should not mix!
