I will preface this with the fact that we went a tad overboard:
For my Matron of Honor & Maid of Honor (only BM's), we paid for 1/2 the cost of their dress (I wanted them in a Vera Wang I loved), they stayed with me in our 3 bedroom Grand Villa @ BW, my mom paid for manis, pedis, massages for spa day, and for their hair and make up.
Their "gift" was navy velour sweat suits, "matron of" and "maid of" tanks, flip flops (with their name in swarovski crystals), and a picture frame.
My flower girl had a "My first man and pedi" at the spa, a matching velour sweatsuit and tank (to be like the "Big Girls"), and a bag full of Disney princess goodies (including the Bride's magazine Cinderella doll from the "dream wedding").
For our readers, we gave a cute three tiered note pad with matching pen.
For the groomsmen, we got them each something from around property that suited each personality. (One got golf stuff, another ESPN, and the usher had just been to Wine country in Cali- so he got wine glasses).
