A pebble's throw away from the Akasaka Mitsuke subway station, the Hotel New Otani (which happens to be in the midst of celebrating 35 years as one of Tokyo's premier hotels) might just offer the solution to savvy travelers' "been there, done that" blues.
You could start by getting married in the chapel (English available, no excuses) and then spend your honeymoon exploring the vast main lobby. A stroll through the New Otani's elegant shops featuring exquisite Japanese artwork, jewelry and other luxuries, could easily push you to make a quick call to the Visa hotline, begging them to raise your card limit.
For a more cultural experience, the hotel boasts an art museum, after which you can take a moment to reflect (on your looming credit card bills) in their sun-drenched atrium. Finally, embark on an international eating extravaganza at one of the hotel's 34 restaurants.
