Hi,
Strictly speaking campsites (and other facilities like toilets etc) are not 'alternatives'. Probably best in a new relation .. 'facilities'?? 

Anyway I'm looking at doing this in Sept, so tidying up the near camp grounds and will probably look at supermarkets and general stores along the way. Probably fill in some of the trail surfaces, generally just paved and unpaved unless an associated way has a more detailed tag and it looks the same. 

Regards.
