thank you for the replies,

I have ruled out most student cards (non-Amex) because the APR is simply too high. Even though I do not anticipate carrying a balance I have been pre-approved on two credit cards for under 10% APR so I do not see the need for a 15% APR student card. About the SPG card, I really do not stay in hotels that much (so far), but I will have to examine it.
