I found the solution on CRS examples
http://wiki.mikrotik.com/wiki/Manual:CRS_examples
Isolation
Port Level Isolation
combined with vlan tagged the final config was
port1 connected to router and hotspot server in vlan35
port2 to next CRS 24ports same config than swich1
port2 to 24 fro rooms, use vlan35 untagged, isolated to each other, but get ip and from hotspot server on vlan 35 port1
now testing and almos ready to send to hotel
feel free to comment or make suggestions
