Oh no - fully understand.
The setttling in bit is so important. We unfortunately ended up doing just that ourselves last year - we acquired Mac just a week before we went on holiday - like you, we have an excellent pet-sitter who lives in whilst we're away, and she took very good care of our little man, but we couldn't enjoy the holiday because we just wanted to be back home with him, and we were worried about the bonding process - needn't have been, I confess, because he was just so full of love he had more than enough to go round, but each cat is different, and it's a very sensible decision that you've taken.
Look forward to see photos of Jasper when he arrives, and hope in the meantime you have a lovely break next weekend.
