Life, Doctor Who and Combom has gotten hold of a page from the Doctor Who Series 5 episode ''Vampire in Venice'' script.
Go Here to see it
From the script page, it appears the episode will mark Rory's first trip in the Tardis. It also clearly indicates that Rory and Amy are engaged and about to be married and that a trip back in time is the Doctor's Wedding gift to them both as indicated by this excerpt:
Anywhere you want, any time you want. One condition: it has to be amazing. The Moulin Rouge in 1890! The first Olympic Games! Think of it as a wedding present. Because frankly it's either this or tokens.
The Doctor again is confronted by a companion's shock at the fact that the Tardis is much larger on the inside than on the outside:
It's a lot to take in, isn't it. Tiny box, huge room inside: what's that about? Let me explain . . .
Right now, from that page, I think the dialogue is smart and interesting. I can't wait to see this episode or the whole of series 5. I'm hoping we'll have an announcement with the trailer today as to when the series will start airing. Could it be Easter weekend? We'll see.
