How do you folks handle tipping when staying 6 or 7 nights? The staff at Conrad HKG were extremely helpful, from the concierge making restaurant reservations, the bell captain (or whatever he's called) getting us taxis, the front desk, etc.

For example, instead of tipping the bell captain every time he got us a cab, I gave him a lump sum when we left. But I missed the second one who worked nights and I didn't know how to handle the concierge desk where there were 3 or 4 different people and I didn't want to tip one and not the other.

Going to both Conrads in March.

Thanks for any advice.
