If prince harry were to divorce meghan and get remarried, would he have another big wedding?

Doubtful his father didn't.

It would depend on who the bride is.  When Harry married Meghan Prince Charles paid most of the costs; when William married Kate her family paid most of the costs. Prince Charles had a low key second wedding because Camilla's ex-husband is still alive, the people's view of her and Diana.  

i can see it ending in divorce down the track .......

well when Prince Charles  remarried , he had a lovely wedding that was televised  ..

not as huge but beautiful  just the same 

nope she would sue him for half , then he cant afford a wedding..lol

They hardly said a thing when Princess Diana's ex-husband Prince Charles remarried.

Prince Charles' wedding to Camilla is probably a good template. It was a civil affair and was conducted with much less fanfare than his first wedding involved. 

I'm no expert on this, but he's not really a "royal" any more.  Or something like that.  He renounced all this and moved to CA.  Not that it matters a lot, but I don't even think he's a true royal to begin with.  He's a dead ringer for James Hewitt!  And he doesn't appear to have a drop of Windsor blood in him.  Yes, I'm a bit bored atm.

he is gone, black sheep / family

he seems like the type that never wanted to get married in the first place. with his position, he was kind of forced to do so. so no, i don't think so. 

It would be a low key wedding..... let's hope it happens though. Meghan lacks the class and intelligence to know how to behave in a dignified manner.
