Upgrade tiers first or craft items?
It seems like crafting is better because it gives you points for the concierge that will get you large chunks of crafting materials you can then use to upgrade.

you can only craft a limited number to start anyway (4 walk of fame stars / 2 constant fountains /etc), so knock those out and get the club points (which in turn can give you more crafting supplies/etc). Then let the coasters/chains pile up and work on the level upgrades.
