The people of Monaco gave the couple a pretty incredible gift. The Monegasque gifted the royal pair with a custom-made white and black Rolls Royce as a wedding gift (since the money for the car would have come out of Monaco's treasury, Grace and Prince Rainier pretty much paid for the car themselves). They rode through the principality in the car after the ceremony, waving to the thousands lined up along the street.
They delayed their honeymoon because of how exhausted they were. After celebrating with guests and concluding their procession through Monaco, the couple headed down to the harbor. The prince's private yacht, the Deo Juvante II, set out to sea so they could begin their honeymoon, but the pair put down an anchor after only a brief sail. "It was so exhausting," Prince Albert revealed to People, noting that they privately "said that when they left on their honeymoon and got on the boat, they both just kind of passed out from exhaustion and had a good night's sleep before they got on with enjoying their honeymoon the next day."
Their honeymoon puts most cruise vacations to shame. After getting a good night's sleep, the Prince and Princess of Monaco left for a seven-week cruise through the beautiful Mediterranean.
