An excellent report. Thailand (usually Bangkok), Brazil (Sao Paulo and Rio) and Spain (Barcelona) are my usual holiday destinations of choice so we have similar tastes.
Just a few thoughts. I agree that nothing can beat the Brazilian saunas for action. I vividly recall my first experiences of Lagoa in São Paulo. The negatives are safety particularly Rio where I have been mugged and the difficulties of getting there from Australia. The added annoyance is the reintroduction of visas.
Barcelona is a wonderful city and certainly safer than the main Brazilian cities. I do like Thermas and frequent it often enough when I’m there although I don’t think it is quite as good as the well know São Paulo and Rio equivalents.
Thailand has a wonderful culture, the people are fabulous, plenty of action although not to the same extent as the other mentioned locations. We agree on that. In summary Bangkok is one those places that I just like being there.
Bangkok in May is my next port of call.
