Disadvantages as opposed to what? If your choice is between implementing a query as a view, and implementing the same query as a SQL statement, then views present no disadvantages.
On the other hand, if your tables are large, and your join complex, you could end up with a query that takes a long time to execute. But whether its a view or not won't affect this.
