I liked that it was easy to add more sites than our main site already had, with little effort - just drag'n'drop from the map! It took ages for each page load (even when caching enabled) so we needed an expensive dedicated server instead of using one off-the shelf VPS or shared hosting plan; overall too much hassle compared to other solutions out there.
No support in English either as far as i know, which made troubleshooting difficult if not impossible by myself alone without help / translation services. We have been able solve all problems ourselves but eventually gave up due time/money constraints. The software allowed us managing easily multiple campsites within minutes after installation whereas before manually adding records would take hours & at least once per week even though most were quite simple changes like increasing capacity etc...
