Go together!

[Mikio91]

Hello,

Two of my colleagues contemplate going on holiday in the same country but not together.
How could I tell them in Japanese Go together! ?

I thought about

いっしょに行ってね！​

Only, it seems to me that いっしょに normally refers to other people + myself. I'm not sure, do I get this right?

いっしょに is OK, but 行ってね sounds rather feminine. I would say 一緒に行ったら？ "How about you guys go together?"

Superb, thankies
