We have the XLP and love it
We have 2 girls who don't always get on , so we opted for the XLP so they can have a 'room each' with plenty of space for a blow up single bed, and room to move around and to store all their clothes etc.
When we have camped they have had 'friends back' to their respective rooms and there's plenty of space for 3 or more girls to crash out and chat in each of the side rooms! ... with our double room in the middle to help give a little distance between the 2 groups if needed!
Our double central room fits a double airbed, and nothing else ... but that's fine as we use the wardrobe for our clothes storage.
One night we opened up all the bedrooms and 'slept together' and the one room seems massive!
The lounge area is also huge! ... and we never felt on top of each other.
The front porch is plenty wide enough for a kitchen unit one side, table and chairs in middle and larder the other side.
The only downside of the XLP over the LP in our opinion is you can't get a front extension for the XLP, whereas a Montana 6 front extension just about fits a LP I believe..... that said, we think we've found a Coleman awning that will do the job!
So I would say, unless you have kids that won't argue and who ae happy to share a very cosy room, then go for the XLP!
