There is one UK cruise web-site which incentives members by giving them a 600 page book on cruising for each submission.
I don't submit reviews there either
Reason I don't submit reviews is
1. Too time consuming.
2. Who the hell cares?
3. I have commented previously that I thought dining in MDR is not good = general response is cruise with them again . Why?
4. My views of cruising are sometimes poles apart from fellow UK cruisers and as this is a US board - don't think they are relevant or helpful to other cruisers.
