Cisco VPN Client not able to connect from certain locations

Dear Experts,

We use Cisco ASA firewall for our VPN so that traveling workers can access shared drives and their Outlook.  Recently, some workers had trouble getting VPN to connect because of the hotel's firewall.  I was informed that I must give them the port numbers they should open so that this problem does not happen.
I am not sure if I know this port, and if it is not hardware dependent, or if this request is even reasonable.
We are using Cisco VPN Client v., and Cisco ASA 5512x firewall.
Please advise.

For Cisco IPSec VPN to work you would have to verify that the following ports are open at the hotel your remote workers are lodging at.

UDP 500 and IP 50 and 51

I would recommend moving to cisco's ssl VPN (AnyConnect), I did for my users, and it works well pretty much everywhere.
