Hi Kestrel,
I live close to Pattaya. All the comments made about the place herein are pretty true but you said that you were thinking of staying at the Dusit Resort which is at the far end of the beach (northern end) and as far away as is possible from Walking Street where much of the 'adult' action is taking place.
If you are a couple and you have kids with you the activities of the local 'ladies' should not be a bother.
Also, as a couple out and about in the evenings, no problem and you may enjoy watching the frantic activity.
Pattaya is the oldest of Thailands resorts. It is now grown from a fishing village in the 70's to the second largest city in Thailand after Bangkok so it isn't as Picturesque as (say) Samui or other more southern islands.
The Dusit Resort is set in it's own grounds and fenced. There is a private beach and swimming pool. Even if you don't want to venture out into town (and that would be a pity coz it's a fun place) you will find everything you need inside the resort itself.
Just be careful late at night. There is crime just as there is anywhere in the world so don't go off the beaten track and take taxis wherever possible. There are hundreds of (so called) baht buses - the pickups with covered seating in the cargo tray - and if necessary you can arrange your own transport with the Dusit.
Sawasdee. I hope you have a very good time.
