Honestly, with the resources out there at our disposal (like this forum) you could probably even do without the consultant. You already found the resort yourself AND you found out about the catholic/legal ceremony. There's so much research available out there that you could do on your own.
When I first started planning, I thought I would get a WC, but seeing how many brides (especially on this forum) do very well without one I decided against it. I think it depends on your comfort level.
