A travel writer who dislikes group trips shares their 2 do's and 1 don't for planning a group vacation.

Planning a vacation, even for one person, requires mental and financial gymnastics. Adding others to the trip increases the logistical complexity.

"I don't like group trips," she declares. "I'll never change my mind. As I age, my opinions become more set in stone."

Although Walker takes five to six trips annually, she has only been on five group trips in total. However, she admits that she's had some enjoyable experiences on larger vacations. "I must say, but I just returned from an amazing group trip," she remarks.

To ensure a smooth trip, Walker offers tips for destinations that are best enjoyed with company, even if you prefer to travel alone like him.

Do: Talk about budget.

She, being a travel writer, acknowledges the various mark-ups that come with traveling and is completely comfortable with it.

It is recommended to communicate your spending plans in advance, including both larger expenses like hotels and smaller costs like meals.

"People often overlook the importance of food in their plans," she remarks. "At dinner, someone will usually complain about the cost."

Discussing the number of fancy dinners, their cost, and the total amount you would like to spend on breakfasts and lunches is essential.

Do: Set deadlines.

These activities, such as winery tours, concerts, and outdoor excursions, require payment and must be reserved in advance. Inform your travel companions of the necessary commitment date.

"Set reasonable deadlines for having activities booked," Walker says.

No one is expecting that they can join or drop out last-minute.

Don't: Be inflexible.

If someone reveals their budget and it is lower than yours, try to find a way to compromise.

"Walker advises against setting unrealistic expectations. If you are aware that someone is on a budget, it is not appropriate to suggest staying at a $3,000-a-night hotel. If budget constraints have been communicated beforehand, there is room for compromise."

If you want to indulge in a hotel room or a meal, not everyone will join you.

According to Walker, the lack of an open discussion about budgeting is the reason for the failure of such trips.
