Find Your Cruise
Firstly you can take as much luggage as your flight allowance will let you...(or if you're sailing from UK as much as you like!) the suitcases will fit under the bed when emptied.
If you are paying your costs in cash then you pay a sum of money to reception on arrival and top up if necessary...or most people give their credit card number and the costs are automatically charged to your account. they will send you statements at intervals over your holiday so you can keep a track of what you're spending.....We find the credit card system the easiest...the on board spending is in pounds sterling so no converting to euros necessary.
