Translation of demonstrate in Spanish

There were two options, a connection flight to Phuket and one to Krabi. Generally, I wanted to reach the western part of the country, because it apparently had better weather this time of year.
I hope that I will have time to go skiing. Maybe it is even better to go at the end of the season. The doctor, however, did not give his diagnosis yet. If I cannot go I will have to find an alternative.
What do you think of the current situation? Like you, I am writing letters, emails and other messages. Tomorrow I will leave, then I will go to my friend in Spain, where we are planing a beach vacation.
