Women going to halls

Q: I have been invited to a “Walima” of a close family relative. The event will be in a hall with a screen to separate men and women. The bride will be on a stage and the bridegroom will (after the nikaah) change into a suit and go to the bride to put the ring on her finger and exchange jewellery. There will also be a lot of non-Muslims attending as well and I expect that women will be inappropriately dressed. It is claimed that there will be no photographs but I suspect that this will be difficult to enforce and control. My son has been requested to recite Qur'an at this function. My questions are:

1. Is it permissible to attend such a gathering?

2. Is it permissible for my son to recite Qur'an here?

My obvious concern is about breaking family ties should I not attend. Please advise.
