Sounds like we're in a similar situation. DS1 is in Size 5 daytime dipes. We size up for night time Huggies overnites and have generally had luck. So right now he's in Huggies Sz 6 overnights. We still occassionally have accidents but generally infrequently.
We also do the following: Insist on him trying to go potty on the potty before bed every night and first thing in the AM. This helps alot. Reducing liquids in the evenings probably would help, too...but since we don't get home until 6:15 and bedtime is 8 pm with dinner in between...well, he gets liquids.
GL!
ETA: Just saw that the potty is being boycotted. DS1 boycotts during the day with us, but generally is good about AM/PM for us. We offered money (he gets to choose a penny, nickle or dime for pee pee and a quarter for poop) and that was a big deal. At daycare they do skittles...so that has worked also.
