2018 is quite unique for people who are seeking Lifetime Elite but are short of a year or so. 2018 will be yiur last opportunity to get “two years” of elite. All what you need to do is to qualify for BOTH SPG and MR under their current rules (25 stays or 50 nights for SPG or 75 nights for MR). I believe this worth some effort for people who are close to LTP so they could be grandfathered to LTPP.
GOOD LUCK ALL TRAVELERS
