I have been to a destination wedding in Italy (close family) but I would say hello no.
First destination weddings are selfish. It’s a forced holiday so the bride and groom can spend less on their wedding. The bride and groom may think it’s lovely but the guests may not. Not everyone wants to take time off, spend a load of money on a place they don’t want to etc especially if they aren’t close family.
The weather in June was 38 degrees so the bride and groom were absolutely melting. Everyone in the photos looked beet red and over heated.
The food planned wasn’t appropriate as it was either hot (we were too hot and didn’t want to eat) or melting in the weather. Drinks got warm very quickly. People got drunk very quickly because of the heat.
The ceremony was all in Italian (obviously) and we had no idea what was going on, what was being said or when it was finished. Found that very weird.
Normally the bride and groom have to be there at least a week before so hear that in mind as you have to register your marriage etc.
Sourcing anything is challenging anything in a different language and while the venue had a wedding coordinator there were a lot of things that weren’t the brides choice.
Flights were expensive because flights to Italy can be. A lot of people close to the couple couldn’t go.
A lot of people left early as it wasn’t for the kids and no one to watch the kids.
OP you have a romanticised view and I think you really need to think about this. I would never go to another destination wedding again (that wasn’t my only one). It’s just a selfish decision.
