This isn't necessarily about II, but something I think you should know as a previous Planet Hollywood owner:
One thing to remember is that for Elara (previously Planet Hollywood) owners exchanging into another Westgate property, you actually get double benefits, meaning you can double what you own. I'm not 100% sure if you can double either your time or your unit, but it's at least one of those.
This also applies to Las Vegas Resorts and Park City Ski Season owners (although Park City Ski season owners should never do that).
This is not something they really talk about much, but definitely inquire by calling Westgate's reservation line. If they don't know what you're talking about, they need to reach out to management because they should know. Ask them to explain the double benefits pertaining to your account.
Double benefits is simple. If you're trying to book 4 weeks, you can double that to 8 weeks. If you're trying to double the unit size, you could book a 1-bedroom and upgrade it to a 2-bedroom. The only thing about double benefits is that you have to relinquish the entire unit for that usage year, meaning you wouldn't be able to use it @ Elara for that particular year. You may also be able to do the same when exchanging into II, but I'm a bit rusty on this so I recommend checking with the reservations team to confirm.
