so rafa and monaco were invited or was rafa invited and he brought monaco with him?
Rafa's trip to Thailand to play Bangkok in 2010 included a luxury holiday on one of the islands as part of the package I think (on top of his appearance fee - nice for some) - he also did the tree planting ceremony etc. Took Monaco, doubles partner Marc Lopez and buddies from Mallorca on the boys trip - so yes Pico was only there because Rafa took him with him. The ceremony etc. was obviously only done by Nadal...
He was clearly amused by the flowers used for garlands - see around he 0:30 mark in the video below - good thing Pico was there for him to have someone to talk to.
