I'll be staying in a hotel (Tampa area) for an extended period of time (6-months) starting in Oct. Looking for suggestions on the best way to maximize points earned.

Was thinking about using Hilton (Homewood Suites) or Marriott (SpringHill Suites or Residence Inn) because they have a kitchen/kitchenette.

I'm gold with Hilton and could do the platinum challenge with Marriott.
