I got a bus about 5 in the morning and I think it only took a couple of hours. Ha Tien is less than 100k from Rach Gia and my memory is that the roads were fine. I kept going to Can Tho. I think there are a couple of other buses to Rach Gia during the day. The bus depot was quite close to town, just across the river.
Ha Tien is a nice little town and there are some interesting places to see, including a couple of nearby beaches.
