Park is referring to Hyde park. This can be cut down to a corner of the park, and include some of the buildings surrounding the park. It would be interesting with some foliage to hide in and maybe some more 2nd story areas. I think this would be a good execution map personally.
Trafalgar would be referring to Trafalgar Square. On this objective map, an EV could be escorted down Whitehall. Once passed the roundabout, the EV could do something similar to bridge where it blows open the doors to the national gallery. Inside the gallery, there could be an extraction of data cores, or possibly a c4 plant to destroy a certain piece of information or a data base possibly.
I personally think that Trafalgar would be fun, with the fountains possibly spraying water onto the floor and fighting up the stairs into the gallery. It would be cool if all the current paintings were included and if shot they fall off the wall or get destroyed maybe (just a thought).
Is this a good idea?
