Some concepts are confused with each other for example, Hunter’s view of sustainability principles and approaches to tourism planning, which means approaches to planning are still due.
There are many grammar difficulties; also do not paraphrase technical terms (e.g. sustainable tourism could not be changed to maintaining tourism/tourism impacts are not the same as tourism perspectives).
No need to add headings of M1,D1, …
Use relevant references and use them appropriately (for example you refer to International Tourism Consultancy Associates for all your case studies, mostly irrelevant or with no justification).
When using destinations as case studies you should provide relevant and reliable facts and figures not generic discussions. Therefore P6 and P7 need significant improvements.
