Pros and Contras of sleeping in the chalet:

Contras:
-There's even MORE mess in there than in the attic, relatively.
-It's also dirtier.
-If "we" were to clean it (the chalet) out:

• a) The flight leaves at -what?- 16:45 => arrives in Doncaster at about 18:00. You're hardly going to start clearing it out then, are you?
• b) We'd start with perfect sunshine and in the middle with all the stuff outside, it'd start raining ... Drip, drip, drip.
• c) Where to put all the stuff? The chairs and tables and rugs?

-We wouldn't be able to get back into the house at night 'cos of the alarm.
-It'd get ubber hot during the day and oober cold during the night.
-There are no beds in there, so we'd have to sleep on the floor once more.
-It's kinda freaky. There could be spyers or burglars could somehow bypass the alarm.
-Would Grandpa/our parents let us sleep there?

Pros:
+Out of the way, so the lounge would be free. "There's no stopping us now...'' => PARTY!!! Heh, just kidding => make as much noise as we want (if a burglar breaks in this could be a prob).
+Functional toilet, well most of the time.
