The 2017 Field Day GOTA Station FAQ states "The GOTA station uses a callsign different from the call used by the group’s main Field Day operation. The GOTA station must use the same, single callsign for the duration of Field Day." Would that mean that appending a suffix, e.g. /GOTA, to my club call sign is sufficient, or should I use my own personal call sign (since I'm in charge of my club's Field Day operation this year)?
ETA: This is for a Field Day operation based in the USA.
