2) Bet on "Place" most of the time. You're more likely to win something more often, thus it's more fun.
3) Place bets for two races each time - that way you're not always getting up and down from your seat.
4) Don't use vouchers and keep your lucky money separate.
5) Follow the tipsters, but not too much. No one, not even those on the inside, knows the outcome of a race, and a placed outsider will often yield more than win bet on a favourite.
