Question regarding subnet and VLAN

I have a big SSID with 160 VLANs (on for each room) On this network I have two subnets:

subnet #1 MGMT 10.1.0.0/16

subnet #2 USER 10.2.0.0/16

There are 160 different rooms, each with there own VLAN. Will the users in the different rooms have the same IPs? Because they are split in VLANs?

  • Example

Room 1:

User 1: 10.2.1.0

User 2: 10.2.2.0

User 3: 10.2.3.0

Room 2:

User 1: 10.2.1.0

User 2: 10.2.2.0

User 3: 10.2.3.0

  • Or will it be:

Room 1:

User 1: 10.2.1.0

User 2: 10.2.2.0

User 3: 10.2.3.0

Room 2:

User 1: 10.2.4.0

User 2: 10.2.5.0

User 3: 10.2.6.0

Is /16 maybe too big for USER subnet then? If they are split by VLAN anyway, then isnt /24 enough??
