Does a hotel need a log-in to respond to an RFP?

No, a log-in is not needed for a property to respond to an RFP in Meeting Evolution.  The hotel contact is either sent an email directly by the planner or an email is forwarded by you as a Rep Company or possibly a GSO.  Within the body of this email, is a link for responding to the RFP entitled Response Link:

The hotelier responding can either click on the link within the email, or may need to copy/paste the link into the internet browser if they are not able to open it from the email.  It is from this link that a hotel responds to an RFP (Request for Proposal). Note: Each Property has a link that is unique to their RFP response.

Refer to How To Respond to an RFP for additional information.
