The couple may be, responsible for covering the travel and accommodation expenses of their bridal attendants, (bridesmaids, groomsmen, and honour attendants). This is an old rule of etiquette, which may still apply in some circles, where an attendant will have to travel to participate as a member of the wedding party. To avoid problems later, make it known what you are prepared to pay for when approaching your potential attendants.

If you have chosen a particularly posh hotel or resort, you might also want to source out alternate accommodations that are close by but a little easier on the wallet so guests can have budget alternatives. Make guests aware of all of their accommodation options so that they can select that which best fits their budget.  Ask for a discount if booking multiple rooms in the same hotel and check what is included.  Getting breakfast included can be a huge saving by the end of the holiday.

Destination Weddings and the Guest Lists?
You can invite as many guests as you wish, however keep in mind destination weddings typically have fewer guests than traditional weddings. You will find more of your guests will be unable to attend due to work or finances and older guest may not be able to travel due to health reasons.  Destination wedding are more ideas for couples that prefer a smaller more intimate wedding,

Destination Wedding Planning
The key to success in planning a destination wedding is to start as early as possible. As mentioned before, you'll need time to do your research about what will be required to get married in the destination of your choice. You'll also need time to talk with the people you intend to invite to get a rough idea of what dates would work for them.

Once a firm date has been set, you need to get busy making decisions early on in the process. All the details, from the biggest the smallest, need to be considered and decided upon. This way you won't end up scrambling to make important decisions under the gun because time has run out -- that is the best way to make the worst decision.

Major Considerations: -

Weather
Civil unrest / Terrorism
Language barriers
Preparation
Accommodation
Catering

Laws / Restrictions
Before getting your heart set on any particular wedding destination, it’s important to do your research and determine whether what you have in mind is ideal to be ideal. Use a travel agent to help you investigate costs and determine what requirements and regulations are in regard to heaving your wedding in the destination of your choice. Some countries only allow citizens to marry in their country, others may have a residency requirement whereby you have to live in the country for 30 days, 6 months, or a year before you are eligible to marry there.

Weather / Upheaval

It is important to determine if there are any travel advisories or weather concerns for the area you'd like to have your wedding. Use the same precautions you would when planning any holiday. Check weather conditions for the time of year (avoid planning your wedding in the middle of typhoon season, for example), check with the relevant body to ensure that there are no travel advisories for the area in question due to political upheaval, civil war, or terrorism.

Matching your Destination with your Expectations

Your wedding concept and the destination you have chosen must be compatible.  It’s really important that you be flexible when planning a destination wedding. You may have ideas of how you would like your wedding to look like that simply aren't compatible with the destination you have chosen. For example, a gown with layer upon layer of satin and tulle at an sea side wedding in a tropical setting, may be simply to uncomfortable.  Just as formal dining under the palm trees, may not be quite a match.

Keep in mind it may not be easy to oversee every detail of your wedding planning, so be prepared to be flexible.
