Sorry for the delay in responding but we've been away over Easter.
PomsMum: You wouldn't be able to walk from the Anantara to town but the hotel had a shuttle service when we were there. It might be worth looking at their inclusive deals, as although I am the kind of person who hardly ever eats in the hotel, we ended up eating there quite a bit as it has great food (also, I was pregnant and lazy!). They have lots of French guests so the Head Chef is French and he is always walking around the restaurants checking that things are up to his standards. He even comes to the breakfast buffet to inspect it every day.
Re. Hua Hin?s beach, it is long and straight and quite dull. If you check out trip advisor and look at traveller photos you will probably see some shots of it. I am probably being spoilt. It is fine ? just not as nice as other beaches in other places. If you are an Aussie (as your name suggests), you?ll have seen WAY nicer at home.
MaggieW: The Sofitel is right next door to the Hilton and both are very much in the thick of things. They are right next to the beach, the restaurants and the shopping (there is even a Boots!). The Anantara is out of town. Probably ten minutes in a taxi or on the shuttle bus. Sorry, but I can?t remember exactly.
The reason why I didn't like the Hilton is that is a highrise and it felt like it could have been a ?70s hotel anywhere in the world. Also, there seemed to be lots of drunk yobs there (please don't take offense anyone who has been there that wasn't this category!) Check out trip advisor. I think the traveller photos and reviews should give you an idea of whether you will like it or not.
However, all in all, I would chose to go to Hua Hin with kids for a short break over other Thai destinations because of the proximity to Bangkok and the (comparative) lack of sleazy sex tourism. If you are thinking of going for two weeks, it is probably worth getting a flight somewhere else in the country that has nicer beaches.
Of course, the current political situation probably puts a slightly different perspective on our Thai holiday next month...
