Travel packages are the same as reward nights, so since those nights could include resort fees, so would a travel package.

Also, consider if you are getting less than the maximum number of airline miles (i.e. a category 7 hotel package is 280K MR points for 70K/77K airline miles) you may want to buy more MR points.

If you had an additional 50K marriott points, you could get an additional 50/55K airline miles (the large amounit is UA only) by redeeming a 330K travel package.

You can purchase up to 50K MR points per year at 1.25 cents per mile (or $12.50 per K miles). Since most people value airline miles at greater than 1.25 cents, you might want to consider this...
