Their jam-packed tour schedule saw the couple attending a Boston Celtics basketball game, as well as formally leading the countdown to Earthshot by lighting up City Hall – and other prominent buildings in Boston – green, in a spectacular visual tribute. But did the couple enjoy any downtime during their time stateside?

It seems that Prince William and Princess Kate had little time to themselves during their whistlestop tour, but the couple no doubt enjoyed the luxurious amenities at the Four Seasons Hotel in the Back Bay neighbourhood where they were staying.
The lavish five-star hotel was the perfect place for the royals to seek some much-needed R&R between official engagements.

Located alongside the Victorian brownstone homes of the affluent Back Bay neighbourhood, which is a hub for designer boutiques, fashion chains, art galleries and patio cafes set in elegant brick townhouses, Four Seasons Hotel Boston was the ideal base for the couple to explore "America’s Walking City."
Though it's not confirmed which room William & Kate stayed in, the hotel's Royal Suite seems the most fitting accommodation for the Waleses.
The expansive sixth-floor suite offers an eight-seater dining room, a media room, a service kitchen and a baby grand piano. The royals could wind down in the evenings in the thick terry bathrobes and slippers, before settling down to sleep on the hotel's down pillows.
The $15,139 per-night Royal Suite also offers a stunning marble bathroom complete with a separate shower and bathtub, plus an additional powder room.

The Four Seasons offers fairly reasonable rates for other rooms in the hotel for those wishing to indulge in five-star luxury, unlike the royals' $19,000 per-night 4,830 sq. ft penthouse suite at The Cove in the Bahamas during their Caribbean royal tour.
The royals stayed in The Cove's most refined lodging offering on-site. The suite is touted as being "immaculately designed to provide guests with luxury, sensuality, and white-glove Bahamian service".
