It does get a little confusing!
My DH and I talked my MIL into coming with us to WDW, where we had a LV room at the GF. We ate at WCC, LTT and CP. Afterward, we enjoyed the EWP. The next day, we ventured to MGM, where you really should use FP for RNRC and ToT. Maybe next year we'll go for MNSSHP or MVMCP!
For a key to the madness, there's a thread stuck near the top of this forum called "Useful Information for Newbies". In it, you'll find a link to a page that lists all of the common abbreviations we use here.
Good luck- it's like learning a different language!
