Multiple or One Project for single team in Fogbugz?

Question

We've been using Fogbugz for a few months now, and have about 6 projects (aside from the default Inbox project for incoming mail).

We work in week-long sprints, so we have set up global milestones for each week to prevent having to enter them multiple times (for each project).

The iteration planner doesn't support planning for multiple projects simultaneously.

As we are sprint planning in a global fashion (across all the projects at once), would having one project with multiple areas be a better fit for this workflow/planning?

Does this go against a design principle of Fogbugz, or will it make some features not work correctly?

The documentation on Projects and Areas doesn't mention pros and cons of one over the other.

I would say that, instead of pros and cons, there's an idea of grouping for the purposes of planning. Planning units should get their own projects, and any natural subdivisions within that unit most likely merit an Area. The main advantages of Areas is being able to have different primary contacts for workflows and organization.

So it seems the overall design concept of Projects is something that is individually planned, and in this situation, all our activity fits into one Project.
