Hotspot Manager

Dear Sir
I am learning mikrotik from few weeks , i have a mikrotik RB100 AHx2 , configured a hotspot server with 6 hotspot profiles .
the interface of the hotspot is eth3 divided into 2 ip pool named as ( passenger pool and crew pool ) each pool has arround 500 ips .
my question is it good to use the Ready Voucher with the Hotspot server to handle arround 150 concurrent users ?
max users on board will be 300 , but concurrent not more than 150 users .

Or is it better to use the ready voucher with the userman ?

thanks alot for your advanced and smooth support
