Hands yes, hugs better to avoid and then just use your imagination to express your love.
With my husband we have many ways to show our love to each other without being offensive for the locals...well I hope... (like the finger kissing, I touch his finger with mine, when we go out in a restaurant...isn't like in ET film now that I think about it??? It may not be like a kiss but it's enough for me to fell all his love). We did not really plan them...they were created with the time.

And just do not do anything you are not too sure in order not to spoil the few days you have with your BF by being worried all the time.
