Re: Visa renewal
How long will you be in the hotel and do you have the new address you're moving to? Hotel should be okay if it's for a few weeks, but of course you'll then need to pay again when you change the address again.
If it's only going to be a couple of weeks, can you not get your post held until you move? Or arrange to collect it from the post office rather than having it delivered? Then once you move in you can do the necessary changes for everything. If it's only a couple of weeks I'd wait until you get the move done.
