you would save $175 on room rate, get free breakfast, and $100 spa credit, for example, at the Trump (also 4PM late checkout, which you wouldnt use, and an upgrade if available, but it would be to a City View Jr Suite. although you could always ask if a Park View Suite is available)
card costs $395/year (you would only recoup about $325 in the trump stay)

you could also just try faxing/emailing/calling a request for an upgrade to a Park View room, because its your honeymoon. someone else might be able to help with exactly what might work best.
