Our wedding is also taking place at the gazebo, although we've opted to have our reception at the Oceana Pool Terrace rather than the Cascade Terrace (we're only having around 35 guests).
Like some of the other ladies here, I was also planning on having a dual legal/symbolic ceremony, but we've just opted to get legally married in Canada first. In as much as we had our hearts set on getting married legally on July 27th, we could not justify the cost (Dreams was charging and additional $350 for legal ceremony, plus bloodwork $220 per person, plus the cost of getting Apostille Birth Certificates $700+). Altogether with getting the documents translated when we got back, all of the additional paperwork and an additional $2000 cost, we said forget it. So we're now going for symbolic only, with the ceremony being conducted by Rev. Marco.
