From what we have witnessed at gatherings and how we use ours, most people use the cabinets more for storage and do their prep/cooking on a table outside the galley. Our cabinets are slightly raised and would clear a low profile item if opened, but we still use a table for the majority of prep/cooking space.
Once you actually start using it, you will realize what I mean. Keep the galley area as clear from clutter as possible. Use a table (small folding, roll-up aluminum or even a piece of plywood an a couple of chairs) and continue using the cabinets to store what you brought along for the convenience.
You can easily fashion extension tables to attach near the edge of your counter space and create that much needed area. You are only limited by your imagination and, sometimes, your budget.
Good luck to you.
