Having said that, as each place has special characteristics, what is it at each place that YOU think would be attractive/enjoyable.
If you say that "beaches are IT", then that provides scope for people to answer.
If you said "the beach is a great attraction, but I also would like to...", then people would be in a better position to offer advice.

WHY would YOU want to go to Dalat?
So, Evahu_210, please give us more information on what YOU think are THE primary objects of attention (parameters) for YOU.
