Here is an eye-witness account of the festivities at Nathadwara during Dhanteras - 1989
In honour of goddess Lakshmi, Shrinathji - Lord/ husband of Lakshmi, wears a regal Charvagha ( Moughal and Rajput formal court dress with four pointed corners ) of green and gold brocade. Several jewels of pearls, diamonds, rubies and emeralds are topped with a plume of peacock feathers set in the gleaming turban. The stele is covered in contrasting red, while the pichavi sets the mood of a royal garden pavilion. Parrots and peacocks perch amid flowering creepers as elephants dance near the base of the pichoi.
Lalan also exuberates royal splendour in his green and gold brocade. Today, all his toys, caskets and utensils are of pure gold. His pichavi depicts three royal pavilions set amidst a beautiful garden, complete with fountains and a fish pond! Radha and Krshna sit in the central pavilion, greeting their numerous guests and friends on this auspicious day. In the foreground, Krshna, Balram and their friends play with the cows specially decorated for the Divali festival.
In late afternoon, Navnit-Priyaji sits in a magnificent glass pavilion set in his own courtyard. Colourful flowers, mosaics of the coloured glass pavilion and silk curtains compete for attention. Colourful gem encrusted chess set along with numerous other games and toys tempt the lord to play to his heart's desire. Gold caskets around him contain such delicacies as sweets, paan, and sweet scented garlands of fresh flowers. Large enamel "surahi" contains sweet sherbets while the delicate "jharis" contain cool waters of the river Yamuna.
In the evening, vegetables arrive by the cart loads in advance preparation for the Divali and Annakut festival. The Lord's kitchen gets very busy and temple servants work around the clock to serve the most delicious food to the Gods.

PS - it would be great to get other people's eye witness accounts of this or other festivals.
