If Your flying the airline set the limit If not you can take as much as you like bearing in mind you need to store the suite cases and their contents in a limited space.
Thomson limit is 20kgs i am going with them next week.
Yes it has been 20 kgs hold luggage plus 5 kgs hand luggage when we have flown with them in Europe and Middle East (dont know about the Caribbean) they have never weighed our hand luggage tho'. If you are not flying you can take what you like and the suitcases fit under the bed....(well they did in our cabin!!
