I'm worried too that he'll freak and we'll have to start back at the beginning. (FYI, he's a 6 yo rescue, my first bird, and I've had him all of 2+months)
But there will be other people staying there and he can be just a

teeny weeny
bit noisy at times. I know, hard to believe with a Sun.
And he will not no way let anybody but me touch him or get too close.
(He came that way

Instant bond both directions.)
Love 'em all.
