Some wallets, including Electrum and my TREZOR, allow you to send to several people in one transaction. This increases the size of the transaction less than sending all the transactions individually and reduces fees. It's also more convenient.
If you're using a wallet which is under your control, instead of a wallet which holds your coins for you (Xapo), you should also be able to customise your fees. If your transaction is low priority, you should easily be able to pay fees of 20-40 satoshi/byte for now and they would get confirmed. You can check http://bitcoinfees.21.co to check how long your transaction will usually take to confirm in the network's current state.
However, be wary of sending transactions until after the chain splits occuring tomorrow. I would say that sending today is a pretty bad idea, especially when there's less than four hours or so until the fork.
You've to pay the fees.
