There is no dearth of partying going on at the party conventions over the next two weeks.  According to USA Today, lobbyists have figured out how to entertain members of Congress and their guests -- all allowed by loopholes in the new ethics law :

The ethics rules bar lawmakers from accepting meals, gifts or entertainment from lobbyists and groups that employ them.

They also prohibit senators and House members from attending lobbyist-funded parties thrown in their honor. But there are exemptions. Members of Congress, for instance, still can snack at lobbyist-funded events if nothing more substantial than finger food is served.

They also can go to "widely attended" gatherings as long as at least 25 people who aren't in Congress also participate and the event is related to their "official duties."

And none of the restrictions applies to functions that either raise campaign money, collect cash for charities or are sponsored by political fundraising committees.
