Thanks for clarification on better defining your use of Newport for summer which is an important subset of the broader definition of Newport platinum. As mentioned, I have tried for summer at Newport using an upgrade and have not been successful over the last 4 years. My lack of success may not be a good example but summer Newport is suppose to be as difficult and some say more difficult a trade than summer Hilton Head exchange.
Using HHI as a parallel, I have 100 percent success in trading 2 two bedroom I own (not GC) when trading into HHI for July, when I prefer to go. In fact I have 100 percent success in trading for the Grand Ocean where we will only trade for with our 2 br. Late August is an easier trade into HHI because of when schools in the surrounding states go back to school. I have 2 trades into HHI for later August using an upgrade. One a studio for a 3 br at Surfwatch last year that I did a retrade later on. One a 1 br for the Grand Ocean I am going this summer beginning 8/17. I have never had successful in trading the studio or 1 br into HHI for July for any Marriott on the ocean ( there are 4).
If you asked about HHI, my experience would tell you to go with the 3 br if you traded for July and wanted to stay on the ocean and a two bedroom if you traded for late August and didn’t care were you stayed. You have some feedback on general trades and good examples of Aruba and Hawaii trades specifically. An HHI parallel means nothing. If Newport is important to you, you need to get enough examples of summer trades to Newport when you can go. If I couldn’t get enough to feel comfortable, I would go with the 3 bedroom.
