If you like Apollo, I'd just take him! You can use the tickets at a later time if you plan to island-hop more, or trade 'em for stuff. They're always good to have around, so I'd personally take him and save the tickets.
do you need help deciding whether or not to take him? if you really want him right now i'd say go for it, if you don't bond with him you can always let him go later and try again.
