We had to do this too! It was added stress that we definitely didn't need.
Unfortunately, we didn't know anyone in the area where we're getting married and had to pay for a hotel for 9 nights. Then on the 10th day we had to have our appointment to give notice... it was all very strict and expensive.
It was such a long time to take off work and have quite limited annual leave especially taking off so much time for the wedding. We couldn't stay the whole time we were there, but did have to pay for it.
Turned out to be a nice break and we got to the know the area where we're getting married really well.
