When we had our caravan, one of the best bits for me was the fact that the dogs slept with us!!! At home, they all sleep downstairs but in the caravan, 2 slept on the double bed with me, and the others had their own special "holiday" crates..... It was great fun and the dogs certainly didn't seem to be spoiled by being allowed on the beds - they just loved it and when they came home, they went straight back to their usual sleeping routine.
You will be hooked after your first trip.
Just a note of caution - please do make sure you have separate insurance for your caravan. Don't assume it is covered by your car insurance, cos it isn't.
Luckily we were insured but have heard many horror stories of people buying caravans and not getting them insured.
Have fun and I am sure you will love it.
