We do an extensive amount of research prior to visiting any locations, or do it after we've investigated (take a look here for more information).
Many of the links here are ones we use ourselves, and since we do so much, this will constantly be updated. For doing research yourselves, feel free to take a look at any of them. Although we are in the UK, if we find something for outside of that area, we'll post it anyway.
No such thing as too much information. ;)
