Where abouts are you looking?
Weve booked through thomsons to get married in sorrento, I can honestly say they have been fab and its a really personalised service (I was worried someone in a call center might end up organising it!) however the three girls in resort are brilliant and are so helpful especially when I'm emailing them constantly being a bridezilla!
The price in the brochure was £700ish I believe for the "package" which includes all the translations and documentation, brides bouquet, buttonhole, cake, prosecco, local fees for wedding etc. we don't want a cake as our reception venue is sorting us one so they're giving us extra bottles of prosecco instead. There's loads of "extras" too which we've booked like photographer (you chose which one you like), extra flowers (ridiculous amount of options), transport, musicians the list goes on.
We also got a massive discount for booking everyone's holiday through them too, discounted everyone's holiday, then knocked off over £500 off the wedding package so were only paying £200! Got deals for reserved seating for half price etc too.
Good luck x
