Khun LA is spot on.
Good idea to come and check Hua Hin out.
As noted above, there are advantages and disadvantages, as with most places.
You have your own transportation, which I think is necessary.
Hua Hin Hospital, the government one, is great; but being the largest hospital between Muang Petchaburi and Muang Prachuap Khiri Khan, it is very very busy in the mornings (need to arrive before 8.00 am, or after 1.00 pm if you want a car park).
